2APS-U Overview
The APS-U provides multi-frequency RTK GNSS capability together with GNSS Heading, L-Band positioning from TERRASTAR, and
wireless communications within a rugged MIL-STD-81 0 housing for the broadest range of applications.
For maximum flexibility, the design is scalable from a single antenna GNSS receiver to full options with Heading, wireless links and L-
Band capability.
The rear panel has an extensive suite of interfaces for data output, timing, event marks, and a second antenna port for GNSS
Heading. Integrated wireless options optional GSM cellular modem and UHF radio modem for transmission or reception of RTK
corrections.
