PSLV-C42 launches 2 foreign satellites
The Polar Satellite Launch Vehicle (PSLV-C42) of Indian Space Research Organisation (ISRO) today (16 Sept 2018, Sunday) successfully launched two satellites -- NovaSAR and S1-4 -- from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota here.

The PSLV-C42 lifted off from the First Launch Pad of SHAR at 10.08 pm (IST). Both satellites were injected into the Sun Synchronous Orbit, about 17 minutes later, at an altitude of 583 km.

The satellites belong to UK-based Surrey Satellite Technology Limited (SSTL), which has a contract with Antrix Corporation Ltd, the commercial arm of ISRO.

NovaSAR carries S-band Synthetic Aperture Radar (SAR) and an Automatic Identification Receiver payloads. The satellite applications include forestry mapping, land use and ice cover monitoring, flood and disaster monitoring and maritime missions. It will be operated from SSTL's Spacecraft Operations Centre in Guildford, UK.

S1-4 is a high resolution earth observation satellite meant for surveying resources, environment monitoring, urban management and disaster monitoring.

This was the 44th flight of PSLV and the 12th flight of the Core Alone version of the vehicle. Core Alone is its lightest version without the six strap-on motors. It is used for launching smaller payloads.

The PSLV launch vehicle consists of four stages, each of which is a self-contained vehicle capable of functioning independently with own propulsion systems.

During the previous launch (PSLV-C41, 12 April 2018 ), the 'XL' version of PSLV with six strap-on motors was used. The vehicle successfully launched the IRNSS-1I navigation satellite to a Sub-Geosynchronous Transfer Orbit.

Preparations began at Sriharikota in mid-July with the process of vehicle integration setting the tone for the launch. Many centres of ISRO contributed to this mission with the vehicle being designed and developed by Vikram Sarabhai Space Centre, Thiruvananthapuram.

The second and fourth stage liquid engines came from Liquid Propulsion Systems Centre, Thiruvananthapuram and ISRO Propulsion Complex, Mahendragiri (TN).

The vehicle's guidance system is from ISRO's Inertial Systems Unit, Thiruvananthapuram, while SDSC SHAR was responsible for solid motor preparation, vehicle integration and launch infrastructure. ISRO's Telemetry Tracking and Command Network provided tracking support.

ISRO Chairman Dr K Sivan congratulated the team soon after the successful mission.

"I am extremely happy that the PSLV-C42 precisely launched two of our customer satellites at 583 km orbit. This was unique night mission executed for the first time by us. The PSLV has proven yet again as a user-friendly vehicle in all aspects. The credit goes to the entire ISRO team and industries. This success will give added energy for industries to make PSLV by themselves. We are going to have 18 missions in the next six months, virtually one launch every two weeks," Dr Sivan said.

Thousands of skilled personnel from ISRO and industries, including many youngsters, played a crucial role in this mission. The Project Director of PSLV is R Hutton, who was also the Mission Director.

 "The PSLV-C42 marks the latest technology and commercial collaboration between India and the UK with the launch of the combination of high resolution optical and radar (SAR) satellites from us," says Sir Martin Sweeting, Group Executive Chairman, SSTL

As on date, ISRO has launched 239 foreign satellites of 28 countries.

Surrey Satellite Technology Ltd (SSTL) has confirmed the successful launch of two satellites, NovaSAR-1, a Synthetic Aperture Radar (SAR) satellite, and SSTL S1-4, a high resolution optical Earth Observation satellite. The two satellites were launched into a 580km sun-synchronous orbit on board the PSLV launch vehicle from the Satish Dhawan Space Centre in Sriharikota, India on 16 September at UTC 16:38 by Antrix Corporation Limited, the commercial arm of the Indian Space Research Organisation.

Sir Martin Sweeting, Executive Chairman of SSTL, said "I am pleased to confirm that successful contact has been made with both satellites and they are in good health. I would like to thank the Indian Space Research Organisation and Antrix for a successful launch which achieves our long-held ambition to deliver low cost SAR remote sensing capabilities and services to our global customers and enhances our Earth observation capabilities with a sub one metre optical mission."

NovaSAR-1 is the first SAR spacecraft to be manufactured entirely in the UK and is a technology demonstration mission designed to test the capabilities of a new low cost S-Band SAR platform. NovaSAR-1 will be the world's first commercial SAR satellite to be operated at a 10:30 equator crossing time, providing time diversity for radar observations by affording increased daylight imaging opportunities in addition to night acquisitions. Synthetic Aperture Radar is a powerful tool for monitoring the Earth from space due to its ability to see through clouds and image the Earth night and day, and a constellation of three NovaSAR satellites could image any point on the globe every day, regardless of local time or weather.

Mission partners signed up for capacity from NovaSAR-1 include the UK Space Agency, Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the Indian Space Research Organisation (ISRO).

The UK Space Agency has invested £21M in the development of NovaSAR-1 and will benefit from access to data from the spacecraft, significantly boosting the UK's sovereign Earth observation capabilities and leveraging additional inward investment to the UK by creating highly skilled jobs in the UK space industry, and stimulating the growth of data analysis services.

Science Minister Sam Gyimah said: "The data from this satellite, backed by a £21 million investment from the Government, will help innovative start-ups develop new apps that could revolutionise the way we live. It's a great example of how we are working with the space sector through our modern Industrial Strategy, ensuring we remain at the forefront of pioneering science and exploration."

Minister of State for the Department for International Trade, Baroness Fairhead, said: "SSTL is a fantastic example of how UK innovation and engineering can have a global impact. It is clear that our space industry is thriving, resulting in significant growth which reinforces the UK's reputation as a leader in the sector."

Dr Dave Williams, Executive Director of Digital, National Facilities and Collections at CSIRO, said "Through our share of NovaSAR-1 tasking and acquisition time we'll extend the significant role CSIRO – Australia's national science agency – already plays in managing a range of national research facilities. We'll be making time on NovaSAR-1 available to Australian scientists. The satellite provides significant opportunities to support a wide range of existing research, further develop Australia's Earth observation data analytics expertise, and create new opportunities in the field of remote sensing."

NovaSAR-1 was designed and manufactured by SSTL, with an S-Band SAR payload developed by Airbus Defence and Space in Portsmouth and an Automatic Identification Receiver supplied by Honeywell Aerospace. The SAR payload has a dedicated maritime mode designed with a very wide swath area of 400km to enable the monitoring of the marine environment, and will provide direct radar ship detection information simultaneously with AIS ship tracking data to assist with the identification and tracking of sea-going vessels. In addition to operating in maritime mode, NovaSAR-1 has been optimised with three additional imaging modes, including a six metre resolution imaging mode, for a range of other applications, such as flood monitoring and agricultural and forestry applications. The satellite has been designed to offer a high throughput of data, observing in a variety of polarisation combinations to additional information to acquisitions in the form of 'colour'.

SSTL S1-4 satellite is a sub one metre Earth observation satellite identical in design to the three DMC3/TripleSat Constellation satellites launched in 2015. A contract to provide data from SSTL S1-4 was signed with Twenty First Century Aerospace Technology Co., Ltd (21AT) in February 2018. As manufacturer and owner of the satellite, SSTL will lease imaging capacity to 21AT for the lifetime of the satellite, designed to be in excess of 7 years. SSTL S1-4 will contribute sub one metre resolution image data into 21AT's existing TripleSat Constellation service, comprising three SSTL DMC3 satellites launched in 2015. SSTL S1-4 is capable of acquiring multiple targets in one pass, utilising spot, strip and mosaic imaging modes and 45 degree off-pointing agility for a range of applications including urban planning, agricultural monitoring, land classification, natural resource management and disaster monitoring. The very high resolution imager on board the spacecraft has been designed and manufactured by SSTL and will acquire sub one metre resolution images in panchromatic mode and sub four metre resolution images in multispectral mode, with a swath width of about 24km.

The systems on board both satellites are being commissioned in orbit from SSTL's Spacecraft Operations Centre in Guildford UK.

Two British-built reconnaissance satellites, one designed to test new radar imaging technology and another to collect high-resolution optical imagery, arrived in orbit Sunday after a successful liftoff aboard an Indian Polar Satellite Launch Vehicle.

The PSLV lit its solid-fueled core stage as the countdown clock reached zero at the Satish Dhawan Space Center on India's east coast. The first stage motor pushed the 144-foot-tall (44.4-meter) rocket, which flew in its least powerful variant with no strap-on boosters, away fro the Indian spaceport on the Bay of Bengal at 1638 GMT (12:38 p.m. EDT).

Liftoff occurred at 10:08 p.m. local time in India, and the PSLV fired into a low cloud deck less than 30 seconds into the flight, disappearing from the view ground-based observers.

The PSLV's first stage motor burned out less than two minutes after liftoff, dropping away as a hydrazine-fueled Vikas second stage engine ignited for a two-and-a-half minute burn. A solid-fueled third stage and a liquid-fueled fourth stage later fired in succession to inject the mission's two Earth-observing payloads into an orbit roughly 363 miles (585 kilometers) above Earth, very close to the flight's target, Indian officials said.

An on-board camera view showed the two satellites, which flew side-by-side atop the rocket on a specially-designed payload adapter, separating from the PSLV's fourth stage, and officials declared the mission a success.

"Today's success, once again, really proved the promise of PSLV as a user-friendly vehicle in all aspects," said K. Sivan, chairman of the Indian Space Research Organization.

One of the satellites, named NovaSAR 1, is the product of a public-private partnership between the British government, UK satellite-builder Surrey Satellite Technology Ltd., and Airbus Defense and Space, which supplied the mission's radar imaging payload from its facility in Portsmouth, England.

NovaSAR 1's S-band synthetic aperture radar, supported by solid-state power amplifiers, is the centerpiece of the tech demo mission, which aims to validate a radar imager lighter and more compact than those flown on most previous radar reconnaissance satellites.

Radar imagers in space can see through clouds, and are sensitive even in darkness, providing an all-weather, day-and-night surveillance capability. Wave emitted by the instrument will bounce off Earth and return to a receiver on-board the satellite, carrying information about the appearance of the surface.

SSTL views NovaSAR as a pathfinder for future lightweight radar imaging satellites that can be developed at lower cost than similar missions in the past. The trend toward miniaturization in space technology has allowed engineers to fit a radar instrument into a smaller package, meaning the imager can fly on a cheaper satellite and rocket.

The British government provided $27 million (£21 million) to partially fund development of the NovaSAR 1 mission, and will be a primary user of the satellite's imagery to ensure the UK's independent space-based reconnaissance capability. The Australian and Indian governments also have agreements to access NovaSAR 1 images.

"The data from this satellite, backed by a £21 million investment from the government, will help innovative start-ups develop new apps that could revolutionize the way we live," said Sam Gyimah, the UK's science minister. "It's a great example of how we are working with the space sector through our modern industrial strategy, ensuring we remain at the forefront of pioneering science and exploration."

NovaSAR 1 is the first synthetic aperture radar satellite entirely built in Britain, and it's the first commercial radar mission to fly in an orbit that crosses the equator at 10:30 a.m., and again in the other direction around 12 hours later, allowing the spacecraft to return day and night imagery. Many radar reconnaissance satellites are in polar orbits that fly north-south over the planet near the boundary between day and night, a so-called "dawn-dusk" orbit.

NovaSAR 1 carries a radio beacon receiver supplied by Honeywell Aerospace to help identify ships observed by the satellite's radar. The satellite will also assist in monitoring floods, crops and oil spills.

The SSTL S1-4 observation satellite, fitted with an optical camera and telescope, accompanied NovaSAR 1 into orbit atop the Indian PSLV. It was also built in Guildford, England, by SSTL, which will supply high-resolution imagery from the new satellite to 21AT, a company founded in China and now based in Singapore.

21AT currently uses images from a constellation of three DMC3 Earth-observing satellites launched in 2015. The new spacecraft launched Sunday is identical to the previous three, according to SSTL.

Both satellites are no bigger than a sports car, and each weighed less than 1,000 pounds (450 kilograms) at launch. The spacecraft also are each designed for seven-year missions, and both satellites contacted ground controllers later Sunday, confirming their health after arriving in space.

The PSLV mission Sunday was designated PSLV-C42, and it was the 44th flight of a Polar Satellite Launch Vehicle, and the fourth Indian launch of this year. SSTL booked the launch with Antrix, the commercial arm of ISRO.

"Congratulations on a truly amazing launch with an absolutely precise injection," said Martin Sweeting, executive chairman of SSTL. "This again highlights the technical excellence of the PSLV launch vehicle.

"This mission, the PSLV-C42 mission, with NovaSAR and the S1-4 satellite, represents also a very close link between the UK and India on space, between ISRO and the UK Space Agency, and between Antrix and SSTL in Surrey," said Sweeting, who attended the launch in India. "This is a complete team which has been working together on these remarkable missions, which comprise an optical Earth observation satellite and the first UK synthetic aperture radar satellite."

Sam Gyimah, the UK's Science and Education Minister, visited SSTL today wh ere he toured the Company's satellite assembly and operations facilities, and viewed the new images from NovaSAR-1. The Minister said: "Yet again we can see UK research and innovation that is truly out of this world. This 'eye in the sky' can capture an image a dozen times wider than the Strait of Dover and the data it provides can help crack problems from illegal shipping to alerting us to damaging pollution that needs to be countered. This satellite, backed by a £21 million investment from the UK Government, is a great example of how we are working with the space sector through our modern Industrial Strategy to remain at the forefront of pioneering science and exploration."

Andrew Cawthorne, Director of Earth Observation at SSTL said "We have worked closely with the SAR experts at Airbus in Portsmouth to develop NovaSAR-1 and the whole team is delighted with these first results - the outcome of space engineering expertise, ingenuity and collaboration. Over the coming weeks our spacecraft operators will continue to test the capabilities of the spacecraft as we task the satellite to image locations around the world, working towards the start of service delivery to our mission partners in the near future."

Mission partners signed up for capacity from NovaSAR-1 include the UK Space Agency, Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the Indian Space Research Organisation (ISRO).

The image of Sydney was taken at night and cropped images taken from the original show Sydney Harbour Bridge, Sydney Opera House, The Royal Botanic Garden, Bondi beach and several boats crossing the harbour. A second close up from the original image shows small boats moored in the natural harbour at Church Point, north of Sydney in a demonstration of the usefulness of SAR for detecting vessels of many different sizes and types, particularly at night or through cloud cover.

The image of Cairo shows the River Nile flowing from Upper Egypt through Cairo and down towards Beni Suef. Urbanisation, cultivation along the Nile, and the non-irrigated desert areas are clearly distinguishable. Cropped images taken from the original show The Great Pyramids of Giza, and the Red Pyramid and Bent Pyramid near Dahshur.

Synthetic Aperture Radar is a powerful tool for monitoring the Earth from space due to its ability to see through clouds and image the Earth night and day, and NovaSAR-1 is the world's first commercial SAR satellite to be operated at a 10:30 equator crossing time, providing time diversity for radar observations by affording increased daylight imaging opportunities in addition to night acquisitions.
