Common GPS knowledge
Why more GPS channels, better accuracy?
General speaking, we need 1 channel per GPS satellite. There are only 30 satellites in the system & why we need so many channels in the GPS receiver/logger? According to...

Suggestion: Use the GPS diagnostic application (e.g. GPSviewer, GPSinfo) to system reset/cold start the GPS. It will reset the GPS registers.

How accurate a GPS receiver can provide?
The greater the number of satellites you GPS can “see”, the more accurate it will determine your position. The number of satellites that your GPS is able to acquire depends...

How GPS determines your position?
A GPS receiver simply measures the travel time of the signals transmitted from the satellites, then multiplies them by the speed of light to determine exactly how far the unit...
