The DGPS Base Stations from Racelogic sends
corrections via a telemetry radio link to your GPS engine to improve positional
accuracy to between 40cm and 2cm, depending on equipment used.
Most VBOXs are compatible with this system. Simply
place the Base Station in a fixed position, let it average the position for 5
minutes, and then you can measure position to a new level of accuracy. For an
application note on the Base Station, please

There are two types available: Base Station 2, for
40cm and 20cm DGPS accuracy; and Base Station 3 for 40cm DGPS and 2cm RTK
accuracy.
As an example, when the BS3 is used in conjunction
with a VBOX3iR5 (a VBOX3i equipped with 50Hz RTK)
then 2cm accuracy can be achieved. The table below lists which VBOX/Base Station
combination is required for specific accuracies.
