How does RADARSAT-2 work?

RADARSAT-2 uses C-band synthetic-aperture radar (SAR). Data may be acquired in any combination of horizontal and vertical polarizations (HH, HV, VV, VH). Resolution and swath width depends on the operation mode; the resolution range is 1 to 100 metres, and the swath width ranges from 18 to 500 kilometres.

What is alos Palsar?

PALSAR was one of three instruments on the Advanced Land Observing Satellite-1 (ALOS), also known as DAICHI, developed to contribute to the fields of mapping, precise regional land-coverage observation, disaster monitoring, and resource surveying. ALOS was a mission of the Japan Aerospace Exploration Agency (JAXA).

What was the 2nd satellite?

What is the use of risat 2br2?

The objective of the RISAT mission is to use the all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, but also for military surveillance.

Is alos Palsar 2 free?

“Japan will provide free and open access to the wide-swathe observation data from the L-band radar satellites, such as ALOS (ALOS/AVINIR-2, PALSAR) and ALOS-2 (ALOS-2/ScanSAR),” stated Ms. Sasaki.

Is alos Palsar free?

Phased array L-band synthetic aperture radar (PALSAR) data from Japan’s Advanced Land Observing Satellite (ALOS-1) mission are now unrestricted, and can be accessed by scientists and researchers around the world.

What is the oldest satellite still orbiting Earth?

Vanguard 1
Vanguard 1 was the first satellite to have solar electric power. Although communications with the satellite were lost in 1964, it remains the oldest human-made object still in orbit, together with the upper stage of its launch vehicle.

Was there a Sputnik 3?

This time, all went well and Sputnik 3 entered its planned elliptical orbit around the Earth, becoming the sixth artificial satellite after its two Soviet predecessors and three satellites that the Americans launched in early 1958. Sputnik 3 reentered the Earth’s atmosphere on April 6, 1960.

WHO launched EOS-01?

PSLV
India sent its first space mission in almost a year with a launch of EOS-01, an earth observation satellite, this afternoon. EOS-01, along with nine satellites from foreign countries, was launched by a PSLV rocket twelve minutes past three.

What is the transmission rate of risat-2?

620 Mbit/s.
RF communications: The payload data are downlinked in X-band at a data rate of 620 Mbit/s. The ISRO/NRSC (National Remote Sensing Center) is the focal point for distribution of remote sensing satellite data products in India and its neighboring countries.

What is the RISING-2 microsatellite?

Launch: The Rising-2 microsatellite was launched as a secondary payload on May 24, 2014 (03:05 UTC) on a H-IIA F24 vehicle (No 24) from the Yoshinobu Launch Complex at TNSC (Tanegashima Space Center), Japan. The launch provider was MHI (Mitsubishi Heavy Industries, Ltd.). The primary payload on this flight wa the ALOS-2 spacecraft of JAXA.

What is the rapidrising-2 mission?

Rising-2 is a cooperative microsatellite project of Tohoku University (Sendai) and Hokkaido University, Sapporo, Japan. The primary objective of the mission is Earth observation with a resolution of ~ 5 m.

What is the orbital period of the RISING-2 satellite?

Orbit: Sun-synchronous near-circular sub-recurrent orbit, altitude = 628 km, inclination = 97.9º, period = 97.4 minutes, revisit time = 14 days, number of orbits/day = 15 3/14, LSDN (Local Sun time on Descending Node) = 12:00 hours ± 15 min. • In February 2018, the RISING-2 microsatellite is operating nominally in its 4th year on orbit (Ref. 18).

When will the RISING-2 project be completed?

The Rising-2 project started in July 2009 and inherited the experiences gained in the design and development of the SpriteSat (Rising-1) spacecraft which was launched on January 23, 2009. The Rising-2 microsatellite is expected to be completed in the summer of 2013.
