Satellites

SPOT 6-7

SPOT-6 and SPOT-7, the first twins of the Spot family, are positioned 180 ° from each other on the orbit. Recurring purchases on a daily basis for any point in this feature.

SPOT-6 and SPOT-7 provide a 1.5m high image with five spectral bands visible, simultaneously detected and positionally overlapping. Standard products can be provided in the natural color category as orthorectic.

AOI Filiz obtains convenience in obtaining data of the desired region with its features given in order and North-South direction.

With its upgraded and coded services, the transmission of information is provided at a high level.

SPOT 5

SPOT-5, the fifth satellite of the Spot series, was launched on May 4, 2002. There are two HRG sensors derived from the HRVIR devices on the SPOT-4 satellite, capable of high resolution detection on the satellite. These sensors can provide data with a resolution of 2.5 meters to 5 meters in panchromatic detection mode and 10 meters of resolution or better in multispectral detection mode.

There is an HRS sensor on the satellite that can detect in panchromatic mode. With HRS, stereo image pairs that can define surface relief can be obtained through forward and backward views. Digital Elevation Models are created from stereo image pairs that provide the height information of the earth.

PLÉİADES

Pléiades 1A and Pléiades 1B operate on the same sun-synchronous circular orbit 180 ° apart. These twin satellites, which produce very high spatial resolution optical data, have the capacity to visit a point on earth twice a day. Due to these advantages, they can be used for both civilian and military observation purposes such as engineering and construction project areas, mines, military complexes, conflict areas, crisis and disaster areas, natural risk areas, evacuation and rescue operations.

The Pléiades 1A was launched on November 16, 2011, and The Pléiades 1B on December 2, 2012. The distribution of the images of the satellites produced by the Astrium company is done by Spot Image.

RadarSAT 1-2

Radarsat-1, Canada’s first commercial surveillance satellite, was placed in orbit on 4 November 1995 and continued to provide images until 29 March 2013. The satellite, whose orbit height is 798km from the ground, uses Artificial Aperture Radar sensors in the C band at 5.3 GHz microwave frequency. Depending on the angle of incidence of the beams to the earth, images with different resolution and coverage area can be obtained. While it can provide an image in an area of 50km to 50km with the highest resolution of 8m, it can give an image in an area of 500km to 500km with 100m resolution.

Radarsat-2 was put into orbit on December 14, 2007 as a joint effort of MDA and the Canadian Space Agency. The term of office is designed as a minimum of 7 years. Unlike RSAT-1 satellite, Ultra Fine Beam mode with 3m spatial resolution has been added, 3mx1m resolution spotlight feature with 18km swath width has been added. The polarization, which is unique in RSAT-1, has been increased to four as HH HV VV and VH, and its capacity has been increased so that the direction of view can be both right and left.

METEOSAT

The second generation Meteosat Program (MSG) covers a series of satellites in geosynchronous orbit. This satellite system program, located in orbit 36000km from the equator, is run by EUMETSAT.
