Remote Sensing Platforms and Types
In this article one can see remote sensing platforms and types with a comparison between different types of sensors. The tabular comparison is made between satellite sensor, altitude, life, sensor bands, sensor resolution, revisit frequency, capacity and swath width all in one image. After visiting various websites this data has been compiled for those who are new in the field of GIS and should not have to spend much time gathering it.
Types of Sensors
Remote Sensing Platforms and Types
| Platform | Range | Types | Sensors |
| Ground Based Platforms | · Short Range (50-100m)
· Medium Range (150-250m) · Long Range (up to 1km) |
· Mobile Hydraulic Platforms (up to 15m height)
· Portable Masts · Towers · Weather surveillance Radar (400 km or less) |
· Spectral reflectance meters
· Photographic systems IR or Microwave scanners · Radio Energy |
| Airborne Platforms | · In between ground and space | · Balloons Based (22-40km)
· Radiosonde (Pressure temp, humidity) · Rawinsonde (Pressure temp, wind, humidity) · Wind finding radar · Aircraft (High Spatial Resolution 20cm or less) |
· High Frequency Transmitter and Receiver
· High Spatial Resolution 20cm or less
|
| Space Borne Platforms | · 100-36000km
|
· Low level Satellites (700-1500km)
· Polar Orbiting Satellites. · Near Polar Orbiting Satellites. · High Level Satellites (about 36000km) · Geostationary Satellites · Space shuttles (250-300km) · Space Stations (300-400km) |
· Polar orbiting satellite have a good spatial resolution, typically 1-50km per pixel
· Meteosat transmits HRI data at 1694.5 MHz, at a data rate of 166.66 kbits/s
