AMSAT-India VO-52 completes 9 years in orbit

On Monday 5 May 2014, AMSAT-India’s VO-52 will have completed nine years in orbit.

During this time it has proved to be a valuable communications resource for the amateur radio community

It gives us great pleasure to inform that ‘HAMSAT – VO-52′ is successfully completing 9 years of fruitful services on 4th May 2014 and entering into her 10th year of services on 5th May. HAMSAT was launched as a piggy back aboard PSLV-C6 on 5th May 2005 (5-5-5). We do hope that the contribution of ‘HAMSAT’ by India/ISRO to the ‘Global Amateur Radio Fraternity’ has served its purpose. It gives us great pleasure and satisfaction to note that ‘HAMSAT VO-52′ has remained as one of the most sought after and favorite ‘Linear Birds’ among the radio amateurs for her sensitivity, strong down link signals, stability and the ease to work.

Though expected to work for two years (mainly, considering the battery), HAMSAT VO-52 has really out lived and still doing strong. Latest telemetry indicates all the parameters and systems to be normal and satisfactory. We do hope that ‘HAMSAT’ would continue to provide her good services to ‘Amateur Radio fraternity’ for many more years.

OSCAR-11 / UOSAT-2 celebrates 30 years in orbit

UOSAT-OSCAR-11 has now been in orbit for 30 years and remarkably its signal on 145.826 MHz FM (AFSK 1200 bps ASCII) is still being received.

OSCAR-11, also known as UOSAT-2, was designed and built by a team of engineers at the University of Surrey in Guildford, Surrey, UK as the successor to OSCAR-9 / UOSAT-1.

It was launched from the Western Test Range at Vandenberg Air Base, in Lompoc, California along with LANDSAT-5 on a Delta 3920 rocket on March 1, 1984.

OSCAR-11 was the most rapidly designed OSCAR, going from inception to launch in only five months. It was also the first amateur satellite to carry a digital communications package into Earth orbit, and the first to be controlled by a CPU running software written in the high-level programming language “Forth”.

OSCAR-11 carries beacons in three amateur radio bands.

The 145.826 MHz beacon transmits FM Audio Frequency Shift Keying (AFSK) 1200 bps ASCII data. It the early years it also transmitted a voice message from the digitalker experiment.

The 435.025 MHz beacon transmitted either 1200 bps FM AFSK or 4800 bps PSK data. This beacon was used to downlink information from the Digital Store and Readout (DSR) Experiment, which includes CCD Earth image data, results from the Particle Wave Experiment, and engineering data from the RCA COSMAC 1802 CPU.

The 2401.5 MHz beacon transmitted FM and PSK signals. Antenna polarization for all three beacon transmitters is left-hand circular (LHCP). Only the 145.826 MHz beacon is now operational.

Radio Ham's Sprite satellites launch in March

On 16 March 2014, two hundred “Sprites” are scheduled to be launched into Low Earth Orbit (LEO), each one equipped with a solar panel, 437 MHz radio transceiver, and a tiny computer, developed by radio amateur Zac Manchester KD2BHC
