LR Optical Missions
The Paz satellite, formerly known as SEOSAR, was launched in February 2018 and is positioned in the same orbit as the German owned TerraSAR-X and TanDEM-X satellites to form a satellite constellation with them.
Paz has a sun-synchronous dawn-dusk orbit, with an altitude of 514 km and an inclination of 97.44 degrees. The nominal revisit period is 11 days (167 orbits within revisit period, 15 2/11 orbits per day). The mission has the capability for multi-mode, multi-polarisation and left and right looking attitudes.
The main instrument on the Paz satellite is similar to TerraSAR-X, an X-band SAR, and features identical ground swaths and acquisition modes to serve the security and the defence needs. The Paz mission is a dual-use mission (civil and defence) funded and owned by the Ministry of Defence and managed by Hisdesat (a Spanish private communications company providing services to the Ministry of Defence).
|Paz||Single or dual polarisation X-band (9.65 GHz) SAR with the following modes: - Spotlight: Imagery of size 10 km x 5 km @ 1m resolution, or 10 km x 10 km at 2 m resolution - ScanSAR: Imagery on a 100 km swath @ 15 m resolution - Stripmap: Imagery on a 30 km swath @ 3 m resolution (single polarization), or 15 km swath @ 6 m (dual polarization).||The satellite was successfully launched on 22 February 2018.|
DMC3 / TripleSat
The TripleSat/DMC3 Constellation was successfully launched on 10 July 2015 from Dhawan Space Centre, India and delivers 0.8 m panchromatic and 3.2 m multispectral high resolution satellite imagery.
The TripleSat satellite constellation consists of three identical optical earth observation satellites, which makes it possible to target anywhere on earth once per day. Satellite imagery is available at 0.8 m high-resolution imagery products with a 23.4 km swath. Both space and ground segments have been designed to efficiently deliver guaranteed timely information.
In terms of product design, the DMC-3 product is very detailed, conformed to the standard and proposes a lot of additional data. The availability of supporting data (RPC, refined ephemeris/attitude data) in the product is a value added component. In terms of product type, the offer is broad spectrum and four processing levels are proposed: L1A, L2A, L3A and "Ortho". In terms of accuracy specification, the instrument focal plane includes five multi linear arrays (spectral bands); each one having six CCDs. In addition, DMC-3 is using two integration stages in multi spectral bands and 16 integration stages for the panchromatic band.
|Earth-i||1-metre panchromatic and 4-metre imager in three spectral bands||DMC3 / TripleSat were built by SSTL and launched in 2015. By combining the coverage from three satellites, the DMC3 constellation was able to revisit a given area daily. Two of the satellites, 3A and 3C, suffered a failure of the primary downlink unit. A fourth satellite was launched in 2018.|
The Korean Multi-Purpose Satellite-3 (KOMPSAT-3) is a high resolution, optical satellite built by the Korean Aerospace Research Institute (KARI) with the mission objective of providing continuity from KOMPSAT-1 and KOMPSAT-2 for Geographical Information Systems (GIS) and EO monitoring applications.
KOMPSAT-3 (Arirang-3) spacecraft was successfully launched on 17 May 2012 (16:39 UTC) from the Tanegashima Space Center of JAXA, Japan. The agile, 3-axis stabilised spacecraft features a body pointing capability of +45o into any direction (cross-track or along-track). This satellite agility permits event monitoring as well as single-pass stereoscopic observations.
KOMPSAT-3 can provide sub-metre images with various imaging modes, including 0.7 m GSD panchromatic image data and 2.8 m GSD multi-spectral image data. It will continue to provide sub-metre imagery to domestic and international users for the applications of public safety, resource management, environmental monitoring, location-based services, intelligence and disaster monitoring.

The ISRO (Indian Space Research Organization) spacecraft Oceansat-3 and Oceansat-3A are envisaged to provide service continuity for the operational users of OCM (Ocean Color Monitor) data from Oceansat-2 as well as to enhance the application potential in other areas. It is a global mission and is configured to cover global oceans and provide continuity of ocean colour data with global wind vector and characterisation of lower atmosphere and ionosphere.
The mission objectives are to provide continuity of ocean colour data with improvements to continue and enhance operational services like potential fishery zone and primary productivity. To enhance the applications by way of simultaneous Sea Surface Temperature (SST) measurements, in addition to chlorophyll, using additional thermal channels, is envisaged in this mission. The mission, in tandem with Oceansat-2 (on availability), will improve the coverage of ocean colour measurements to every 24 hours and wind vector measurements to every 12 hours.
MOS-1 was Japan's first EO spacecraft, operating in a sun-synchronous orbit with a repeat period of 17 days. It was launched in February 1987 and extended to November 1995, with MOS-1b following in February 1990 and ending in April 1996.
Both satellites carried the Multispectral Self-Scanning Radiometre (MESSR) with four wavebands (visible and near-infrared) at 50 m resolution and the Visible and Thermal Infrared Radiometre (VTIR) with one waveband in the visible, two in the thermal infrared and a water vapour absorption waveband at 900 m spatial resolution. There was also a passive Microwave Scanning Radiometre (MSR).

The Argentinean Satélite Argentino de Observación COn Microondas (SAOCOM) mission comprises of two satellites phased at 180° that carry an L-band SAR instrument. They provide medium spatial resolution (10 x 10 m to 100 x 100 m) data at a frequent revisit time (eight days once both satellites are operational). The satellites are right and left looking, with 400 km ground range access. Together, they will acquire 450 minutes of satellite data per day.
SAOCOM exploits the Terrain Observation with Progressive Scans (TOPS) observation mode [RD-40] as its primary mode. The TOPS mode is currently used in Sentinel-1 but until now has never been used at L-band.
The first of two satellites, SAOCOM 1A, was launched on 7 October 2018 into a Sun-synchronous orbit polar orbit, with a 16 day repeat cycle and 6AM local time ascending node. The same orbit is planned to be used for the second satellite, SAOCOM 1B, which is planned to be launched in Q1 of 2020.
|SAOCOM||Medium-resolution SAR sensor in L-band (full polarimetric)||The constellation is composed of two satellites (SAOCOM 1-A and 1-B). The first satellite was launched in October 2018, the second satellite is expected for Q1 2020.|
GHGSat-D, known as Claire, is a greenhouse gas monitoring demonstration satellite, which was successfully launched in June 2016.
GHGSat-D has a field of view of approximately 12 km x 12 km and spatial resolution of less than 50 m. Its primary instrument, Wide-Angle Fabry-Perot (WAF-P), is an advanced miniature hyperspectral SWIR imaging spectrometre for monitoring targeted greenhouse gas emitters.

The JAXA Global Change Observation Mission (GCOM) consists of a constellation of two medium-sized spacecraft with the provisional names of GCOM-W and GCOM-C. GCOM is seen as a follow-up programme to ADEOS-II (launched in December 2002) with the overall objective to contribute to global change research through long-term (> 10 years) sustained observations with corresponding data sets.
The GCOM-C satellites carry a Second Generation Global Imager (SGLI), an advanced multi-purpose Visible and Near InfraRed (VNIR) Imager. The first satellite in this series, GCOM-C1, was successfully launched in December 2017.
|JAXA||Second-generation Global Imager (SGLI): Imaging multi-spectral radiometres (vis/IR) and Ocean colour instruments.||GCOM-C/Shikisai was successfully launched on 23 December 2017. JAXA started the observation with SGLI in January 2018 and continues its nominal observation operation.|
TanSat (also known as CarbonSat) was launched in December 2016 as part of the Chinese space program. It is the first mini-satellite of China dedicated to the carbon dioxide (CO2) detection and monitoring in the Earth's atmosphere, and is equipped with two dedicated instruments; the Carbon Dioxide Spectrometre (CDS) and the Cloud and Aerosol Polarimetry Imager (CAPI).
CAPI is a wide field of view moderate resolution imaging spectrometre with polarisation-sensitive channels, and collects data concurrently with CDS to compensate for errors in the spectral data caused by clouds and aerosols.
The main objective of the TanSat mission is to retrieve the atmosphere column-averaged CO2 dry air mole fraction (XCO2) with precisions of 1% (4 ppm) on national and global scales. The scientific goal of the project is to improve the understanding on the global CO2 distribution and its contribution to the climate change, and also to monitor the CO2 variation on seasonal time scales.
