Amateur radio satellites

Satellites

Passes over your location, a live map and the frequencies of every working amateur satellite. It is all worked out in your browser: your location stays on your device.

The passes, the map and live tracking need JavaScript. The frequency list, the QO-100 pointer and the questions below work without it..sat-app { display: none; }

QO-100 dish pointer

QO-100 (Es'hail-2) is a geostationary satellite at 25.9° East with two amateur transponders. It stays in one place in the sky, so a fixed dish is all you need.

From Johannesburg (KG43XU)

Azimuth (true) 350.8°

Elevation 59.1°

LNB skew 8.2° anticlockwise

Azimuth (magnetic) –

LNB skew is seen from behind the dish, facing the satellite. Azimuth (true) is from true north. A compass shows magnetic north: use the magnetic azimuth, worked out for the magnetic declination where you are.

Transponder	Uplink (MHz)	Downlink (MHz)
Narrowband	2400.000–2400.500	10489.500–10490.000
SSB, CW and narrow digital modes. Beacons on 10489.500 (CW), 10489.750 (PSK) and 10490.000 MHz (CW). Uplink right-hand circular, downlink vertical.
Wideband	2401.500–2409.500	10491.000–10499.000
Digital amateur television (DVB-S2). Beacon on 10491.500 MHz. Uplink right-hand circular, downlink horizontal.

Questions and answers

How do I work an FM satellite?

Pick a pass that climbs high, say 30 degrees or more. A minute before it rises, listen on the downlink; when you hear the satellite, transmit briefly on the uplink with the CTCSS tone if one is listed (SO-50 needs 67.0 Hz). A dual-band handheld and a small hand-held Yagi such as an Arrow are enough. Give your callsign and locator, keep it short, and listen more than you talk: the satellite is one channel shared by everyone under it.

What is Doppler shift?

A low satellite moves at about 7 km/s, so the frequency you hear is higher while it comes towards you and lower as it goes away: up to about 3.5 kHz either way on 2 m and 10 kHz on 70 cm. On an FM satellite, tune the downlink down in 5 kHz steps through the pass. Live tracking on this page shows the corrected uplink and downlink while the satellite is above your horizon.

Do I need a licence?

To transmit, yes. In South Africa you need an amateur radio licence from ICASA, which you get by passing the Radio Amateur's Examination (RAE); the Get licensed page explains how. Anyone may listen: hearing the ISS or a satellite beacon on a scanner or an SDR is a good first project.

What do I need for QO-100?

QO-100 is geostationary at 25.9 degrees East, so from South Africa it stays in one place in the northern sky and a fixed dish works. To receive the narrowband transponder: a dish of 60 cm to 1 m, a 10 GHz satellite-TV LNB (a stable or GPS-locked one makes tuning easier) and an SDR or receiver at the LNB's output, around 739 MHz. To transmit: a few watts on 2.4 GHz into a right-hand circular feed such as a patch or helix. The pointer above gives azimuth, elevation and LNB skew for your place.

Why do some satellites work only in sunlight?

Some old satellites have batteries that no longer hold a charge, so they run only while their solar panels are lit. AO-7, launched in 1974, is the best-known: it works in sunlight only and still relays SSB and CW. The map shows which satellites are in sunlight and which are in the earth's shadow, and live tracking shows which part of a pass is sunlit.

What do AOS, TCA and LOS mean?

Acquisition of signal (AOS) is when the satellite rises above your horizon, the time of closest approach (TCA) is the highest point of the pass, where the Doppler shift passes through zero, and loss of signal (LOS) is when it sets. Times here are for a clear horizon; the minimum elevation leaves out passes that stay lower than that.

Which satellites should I try first?

The FM voice satellites: one uplink, one downlink and an ordinary dual-band radio. After that, the SSB linear transponders such as RS-44 and AO-7 carry several contacts at once but need an SSB radio and careful tuning. For digital, the ISS APRS digipeater on 145.825 MHz works with a handheld and a TNC or an APRS radio.

Is my location sent anywhere?

No. The passes are worked out in your browser from orbit data on this site. Your locator or position stays on your device, where it is remembered for your next visit.
