The RBV instrument on-board Landsat 3 had an improved 38 m ground resolution and used two RCA cameras which both imaged in one broad spectral band (green to near-infrared; 0.505–0.750 µm) instead of three separate bands (green, red, infrared) like its predecessors. Jonathan's Space Page. The ground sampling interval of the MSS was 57 m (187 ft) to 79 m (259 ft), which is medium resolution.

[14], Specific locations for Landsat 3's data can be found by using the World Reference System (WRS). Visit Landsat 1-5 MSS for more information. The Landsat program’s technical and scientific success together with political and economic pressures lead to the decision to commercialize an operational Landsat. In December 1979 the Soviet Union invaded Afghanistan. The second was the satellite equipment, and the third the ground data centers.

The cameras each had a 98 kilometers (61 mi) square viewing range, and combined the range was 185 km (115 mi).

Countries that cannot afford their own satellite are able to use the data for ecological preservation efforts and to determine the location of natural resources. The most recent, Landsat 8, was launched on February 11, 2013.The instruments on the Landsat satellites have acquired millions of images. [2] The data collected during Landsat 3's lifetime was used by 31 countries. [2] The data collected during Landsat 3's lifetime was used by 31 countries. The sensor weighed 64 kilograms (141 lb), required 50 W of power, and had a maximum 75 meters (246 ft) resolution. Landsat 3 decommissioned on September 7, 1983, beyond its design life of one year. 80-meter ground resolution in four spectral bands: Six detectors for each spectral band provided six scan lines on each active scan, Ground Sampling Interval (pixel size): 57 x 79 m, Scene size: 170 km x 185 km (106 mi x 115 mi), Manufactured by General Electric (GE) Astrospace, Solar array paddles extend out to a total of 4 m (13 ft), 3-axis stabilized using 4 wheels to +/-0.7° attitude control, Twin solar array paddles (single-axis articulation), S-Band and Very High Frequency (VHF) communications, Hydrazine propulsion system with 3 thrusters. The cameras were structurally isolated from the satellite so that they could maintain their alignment.

Landsat 3's RBV had a resolution of 40 meters (130 ft), which was twice the resolution of Landsat 1's 80 m (260 ft). The objective of Landsat 3 was to extend the period of space-acquired Earth imagery, started by Landsat 1 and Landsat 2.The satellite was placed in standy mode on March 31, 1983 and decommissioned on September 7, 1983. "Satellite Catalog". Landsat 3: Űrügynökség: NASA: Típus: Földfigyelő műhold: Indítás dátuma: 1978. március 5. [8] The scene size for the scanners of the MSS was 170 kilometers (110 mi) to 185 km (115 mi), which is the area the sensors could survey per scan. The sensors aboard each of the Landsat satellites were designed to acquire data in different ranges of frequencies along the electromagnetic spectrum (View Bandpass Wavelengths for all Landsat Sensors).The Multispectral Scanner (MSS) carried on Landsat 1,2,3,4 and 5 collected data in four ranges (bands); the Thematic Mapper (TM) sensor on Landsat 4 and Landsat 5 included those found on … This was eventually renamed to Landsat. [14], Specific locations for Landsat 3's data can be found by using the World Reference System (WRS).

[9][8] Unlike the previous two Landsat missions, a thermal band was built into Landsat 3's MSS, but this instrument failed shortly after the satellite was deployed on July 11, 1978.

Combined with horizon scanners, sun sensors, and a command antenna, the ACS was able to control the spacecraft in all three axes to plus or minus one degree. Retrieved March 18, 2014. [8] The scene size for the scanners of the MSS was 170 kilometers (110 mi) to 185 km (115 mi), which is the area the sensors could survey per scan. [2] The satellite had a very similar designs to Landsat 1 and Landsat 2. To find any specific location on Earth, a row and path number are required; for example, Row 60 is at the equator. [4] It was made up of a double reflector telescope, scanning mirror, and detectors.

The satellite had a repeat cycle of 18 days and had an equatorial crossing time of 9:30 a.m. mean local time (+/- 15 minutes). Landsat 5 ist ein US-amerikanischer Erdbeobachtungssatellit, der von 1984 bis 2013 in Betrieb war. "NSSDC Master Catalog". 896 KB - JPEG, 946 x 710 [2] Video was transmitted back to Earth in both real time and from the recorders at 2265.5 MHz. Each spectral band had different scientific uses. [10] The thermal band would have enabled the MSS to have remote sensing capabilities during the night.
Countries that cannot afford their own satellite are able to use the data for ecological preservation efforts and to determine the location of natural resources. [4], Landsat 3 carried a Multispectral Scanner, built by Hughes Aircraft Corporation.

[7], The Return Beam Vidicon (RBV) was designed at RCA in Princeton, New Jersey.

The primary mission of the MSS was to obtain data for agriculture, forestry, geology, and hydrology, but the MSS could also collect information for oceanography and meteorology purposes. The data are useful to a number of applications including forestry, agriculture, geology, regional planning, and education.

[4] It contained two cameras to cover the 0.53 to 0.75 micrometer spectral band. Landsat, Serie amerikanischer Erderkundungssatelliten auf fastpolaren (Inklination i = 99º), sonnensynchronen Bahnen.Landsat 1 war eine verbesserte, größere Version der NIMBUS Satelliten und war ab 1972 im Einsatz. Tidak seperti kemudian Landsat-Landsat, Landsat 3 dikelola sendiri oleh NASA. [10], The data from Landsat 3 was used by over 400 programs in 31 countries. For example, Bolivia spent $10,000 on data which was used to discover vast lithium deposits, while United States companies have invested more than $136 million for further exploration.

[2] Video was transmitted back to Earth in both real time and from the recorders at 2265.5 MHz. Hero’s Stadium in Kingston, Jamaica on April 22, 1978. The MSS sensor on Landsat 3 originally had five spectral bands, but one failed shortly after launch. Landsat 3 is the third satellite of the Landsat program.
