Figure 4 Options/Shutdown

To use previous run data will help to speed up the TTFF for the next fix Server aiding gives you the complete satellite almanac from the sky User input gives aiding over the actual position within 150km distance System will use time (10s error) or internal satellite models

Aiding data for next run saves the position data if you want to use previous run information’s Set the box RTC will ceep the real time clock running if the device will be shut down

Figure 5 Options/Automated Runs

Figure 6 Options/Advanced

Automated runs help to do several runs after an other to determine for example average TTFF over 10 runs. It helps also to do some tests over night without the need to restart the software again by hand

Recording will help to store the name for diagnostic files also the position files will be saved with the same names. With the NMEA output you can simply connect a mapping program to display the actual position on a real map
