The Goldstone main antenna, DSS14, is a fully steerable,
70-meter, parabolic reflector with horn feeds. Its 500-kilowatt transmitter is the world's most powerful one at X-band (8560 MHz, 3.5-cm).
|
 |
Bistatic experiments using DSS-14 transmissions and
reception of echoes at DSS-13, a 34-m antenna 22 km away, have been
conducted on several very close targets.
|
Bistatic experiments employing transmission from DSS-14 and reception of echoes at the 27-antenna Very Large Array ( VLA) in New Mexico have synthesized a beamwidth as small as 0.24 seconds of arc, vs. 2 minutes of arc for single-dish observations with Arecibo or Goldstone. In coming years, bistatic observations between Arecibo and Goldstone, or using transmission from Arecibo or Goldstone and reception at the 100-m Greenbank Telescope (GBT), now under construction, should prove advantageous for outer-planet satellites and nearby asteroids and comets. Test observations using transmission from Goldstone or Arecibo and interferometric reception with the 10-antenna Very Long Baseline Array (VLBA) are planned for 1998, and in principle can produce resolutions near a milliarcsecond.
