“…AODA data reduction algorithms were extensions of well‐established navigation solutions developed at JPL for deep space missions. While planetary spacecraft rarely experience the dynamic environment of the shuttle, a Kalman filtering approach was easily tailored to it [ Wong et al , 2001; Duren et al , 1998]. Instrumental effects in the cameras, saturation of the LEDs, blinding of the star cameras due to shuttle wastewater dumps, etc., required prefiltering of the data, including some editing by hand.…”

The Shuttle Radar Topography Mission produced the most complete, highest‐resolution digital elevation model of the Earth. The project was a joint endeavor of NASA, the National Geospatial‐Intelligence Agency, and the German and Italian Space Agencies and flew in February 2000. It used dual radar antennas to acquire interferometric radar data, processed to digital topographic data at 1 arc sec resolution. Details of the development, flight operations, data processing, and products are provided for users of this revolutionary data set.

“…To avoid the problems with repeat-pass inter ferometry, SRTM acquired its two images simultaneously SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Space Shuttle Endeavour in 1994 [Evans et al, 1997] in a cooperative project between NASA and the German and Italian Space Agencies. To collect the interferometric data, a 60-m mast, additional C-band antenna, and improved tracking and navigation devices were added ( Figure 1).…”

On February 22, 2000, the Space Shuttle Endeavour landed at Kennedy Space Center, completing the highly successful 11‐day flight of the Shuttle Radar Topography Mission (SRTM). Onboard were over 300 high‐density tapes containing data for the highest resolution digital topographic map of Earth ever made. SRTM is a cooperative project between the National Aeronautics and Space Administration (NASA) and the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense. The mission was designed to use a single‐pass radar interferometer to produce a digital elevation model (DEM) of the Earth's land surface between about 60 north and 56 south latitude. When completed, the DEM will have 30‐m pixel spacing and about 15‐m vertical accuracy. Two ortho‐rectified image mosaics, one from the ascending passes with illumination from the southeast, and one from descending passes with illumination from the southwest, will also be produced (Figure 1).

“…Consequently, the remaining errors should be caused only by the InSAR measurement method and the instruments used. A pre‐flight instrumental SRTM errors budget was published by Duren et al [1998].…”

An attempt was made to experimentally assess the instrumental component of error of the C‐band SRTM (SRTM). This was achieved by comparing elevation data of 302 runways from airports all over the world with the shuttle radar topography mission data product (SRTM). It was found that the rms of the instrumental error is about ±1.55 m. Modeling of the remaining SRTM error sources, including terrain relief and pixel size, shows that downsampling from 30 m to 90 m (1 to 3 arc‐sec pixels) worsened SRTM vertical accuracy threefold. It is suspected that the proximity of large metallic objects is a source of large SRTM errors. The achieved error estimates allow a pixel‐based accuracy assessment of the SRTM elevation data product to be constructed. Vegetation‐induced errors were not considered in this work.
