More Compass Points: Tracking China’s MEO Satellite on a Hardware Receiver

In 2000 China deployed the Beidou-1 navigation system. Originally this S-band system provided ranging information via geostationary satellites that operate as transponders. This system design required bulky two-way radios, had a limited capacity, and coverage was restricted to East Asia.

GNSS Over China: The Compass MEO Satellite Codes

On April 14, 2007 (local time), China launched the Compass M-1 satellite. This satellite represents the first of a new global navigation satellite system (GNSS) that is planned to have a total of 35 satellites. Unlike prior Chinese navigation satellites, Compass M-1 broadcasts in L-band, using signal structures similar to other GNSS systems and sharing frequencies near to or overlapping those of GPS, Galileo, and GLONASS.

About That Cover

I opened the PDF with this month’s cover design from our art director, Tim Jordan, about five minutes after I picked up the morning newspaper. In the paper, a front-page article described our local school district’s plans for starting what would eventually become a 12-year immersion program in Mandarin (putonghua or guoyu).

Compass MEO Satellite Signals

On April 13 2007, the People’s Republic of China launched the first middle earth orbiting (MEO) satellite in its Compass GNSS system, 21,550 kilometers (or about 13,200) miles above the Earth. The spacecraft began transmitting signals on three frequencies within a few days, much more quickly than operational satellites in other GNSSes.
