SPAN-CPT Operation

Before operating the SPAN-CPT system, ensure that the installation and set up instructions in Chapter 2, SPAN-CPT Installation on page 13 were completed.

Use the NovAtel Connect software to configure receiver settings and to monitor data in real time, between a rover SPAN-CPT system and base station.

SPAN-CPT system output is compatible with post-processing software from NovAtel's Waypoint Products Group. For information about Waypoint, visit our Web site at www.novatel.com/products/software/ waypoint-products/.
