ALIGN® Enabled

Building on NovAtel’s successful SPAN-SE-D enclosure, we offer our ALIGN heading solution as an option on the SPAN-IGM-A1. ALIGN can be activated by pairing the SPAN-IGM-A1 with an external ALIGN enabled receiver such as our FlexPak6™.

Improved Accuracy

NovAtel’s Advance® RTK improves real-time performance and accuracy. For more demanding applications, Inertial Explorer® software from our Waypoint® Products Group can be used to post-process SPAN data to provide the highest level of accuracy.
