Artists Impression of Antares Launch from Wallops Island, Virginia

The amateur radio satellite Dove-1 (145.825 MHz AX.25 FM) was originally planned to launch on the Antares launcher on February 28 but reports indicate it may be Fall before it is launched. reports that on February 21 Orbital Sciences Corporation announced a further slip and the launch of Antares could now be delayed until as late as September. Read the report here.

Dove-1 was built by Cosmogia and is a 3U CubeSat with a total mass of about 5 kg.

Its 145.825 MHz 1200 bps AFSK AX.25 FM downlink will transmit telemetry data, including temp/power supply/current/RSSI/solar vector/acceleration, approximately every 30 seconds. The beacon can transmit at up to 1 watt and will use a quarter wave monopole antenna cut from a tape measure.

It also has a 2.4 GHz half-duplex, spread spectrum radio with patch antenna that will be used for main payload downlink and telecommand uplink. The data rate will be 115 kbps.

The planned orbit is 280 by 270 km at 51.6 deg inclination which will give Dove-1 a lifetime of about 2 weeks before re-entry.
