By Inside GNSSIn a race with the U.S. to develop a laser communications network in space, China’s BeiDou GNSS has conducted an inter-satellite and satellite-ground station experiment using using lasers rather than the usual radio signals. The technology could potentially transmit data a million times faster than by radio signal to almost any location. Some experts say it could increase satnav accuracy by a factor of 6 to 40

By Inside GNSSAs the final BeiDou satellite reaches geostationary orbit, experts in the satnav community worry about security implications of the now officially operational Chinese system. As a two-way rather than a one-way communication system, BeiDou differs in two key aspects from other GNSS:
By Inside GNSSIn a feelgood two-and-a-half minute video cartoon aimed well below its audience’s head, the XinhuaNet.com news service explains BeiDou advantages over GPS and other GNSS. Principally, the script stresses the satnav system’s two-way short message service (SMS) texting capability that can stand in for cellular communications in remote areas and in case of natural disasters that may disable cellular base stations.
Set to a loping synthesized country rock soundtrack, the entertainment-with-a-message follows a passenger bus through a remote desert. When Buzz the Driver, spooked by a snake, deviates from his planned course, a BeiDou monitoring station quickly detects the error, generates an alarm and sends a message: “Hey, keep yourself focused!”
The animation gives a nod to other GNSS by stating that “Me and other family members are compatible and interoperable at the user level, which allows us to work together.”

The China Satellite Navigation Office (CSNO) announced completion of two years of testing of BeiDou inter-satellite links, an innovative feature of the GNSS that will reportedly produce greater accuracy for users on Earth. The test campaign encompassed 29 satellites of the third generation (BDS-3) of the now global system.
