The SR530 is a 24 channel, dual frequency receiver with on-board RTK. It
provides outstanding performance for every type of GPS surveying. The SR530
Designed with the RTK in mind, the SR530
can be used as a reference or a rover It can be set to send or receive.
I have the SR530, TR500, AT502 needs a housing but works just fine, and
Pacific Crest radio I think the model PDL6FU but I need to look at that. 4-6
batt and a charger.
