Most GPS vehicle tracking systems use a “cellular” wireless telephone carrier system to collect position information from the fleet in the field and transport that information back to headquarters. You may see acronyms such as GSM or GPRS describing the system. The RavTrack system uses a very different approach, that of local user based radio. These [...]
Fast GPS reporting with TDMA timeslots RavTrack is very fast at reporting the positions of even large fleets over a single radio channel because each RavTrack transponder is assigned a specific time slot in which to transmit, avoiding interference which may occur if multiple devices were permitted to transmit simultaneously. The fact that all transponders [...]
TDMA, or Time-Division-Multiple-Access is a very effective way of allowing a lot of radios to share one radio channel. Used extensively in GSM cellular and APCO public-safety systems, TDMA excels at allowing quick and reliable access to radio channels. It allows 2-10 times more radios to share a radio channel than conventional carrier-sense methods. This [...]
The accuracy of a position determined by using a GPS receiver is limited by the accuracy of the GPS signal itself. The US government controls the precision of the GPS signals sent from the GPS satellite constellation. It varies from day to day, and the following graph shows historically, how precise the GPS position information [...]
