PACSAT (Packet Radio Satellite) was an AMSAT microsatellite launched on the first ARIANE ASAP flight V35 with SPOT 2, on the 22 January 1990 into an 780 km sun-synchronous, 98 degree inclined orbit.

It is dedicated to amateur digital Store and Forward packet data communications at 1200 bps. It is box shaped with dimensions of 213 × 230 × 230 mm, with four solar panels and weighs 13.34 kg. Uplink frequencies are 145.90, 145.92, 145.94, and 145.86 MHz FM 1200 bps Manchester FSK, and downlink frequencies are 437.0513 MHz SSB, 1200 bps RC-BPSK 1200 Baud PSK. A beacon is also carried at 2401.1428 MHz. It was reported to be operational in March 1999.
