GPS+ technology.

The GPS receiver inside the G-Series rally computer is much more sensitive than that found in a smart phone or sat-nav device. Combined with an external roof mounted antenna the high-quality receiver is able to deliver accurate distance and speed measurements almost anywhere on the planet.

However, like all GPS systems, there are some limitations. When travelling through dense forest, tunnels, or around tall buildings the GPS signal can be degraded reducing accuracy. For most competitors this will rarely be an issue, but for those who regularly operate in difficult environments and require very high accuracy this performance loss might be unacceptable.

To address this Monit has developed its unique GPS+ technology. By combining the signals from a traditional wheel sensor and the GPS receiver, the GPS+ system is able to maintain high-accuracy operation in all situations.

How it works.

1. While a good satellite signal is available the rally computer operates from GPS alone, eliminating the need for time-consuming calibration and the error caused by wheel spin. In the background the GPS+ software continuously calibrates the wheel sensor against the GPS measurements.

2. If the satellite signal is lost the GPS+ software automatically switches operation to the wheel sensor. Accurate measurements will continue uninterrupted.

3. When the satellite signal is restored operation seamlessly switches back to GPS.

Note: If no wheel sensor is connected the unit will add the straight line distance between where the GPS signal is lost and regained instead.

Wheel sensor only mode.

If you are competing in events where GPS is not allowed the Monit G-Series includes the ability to disable the GPS system completely. When this is done it will operate from a wheel speed sensor just like a traditional rally computer. All other functions will still be available.
