APS-3L

The APS-3L features a high precision GNSS satellite

receiver with embedded L-Band capability. It is
designed to provide seamless RTK and PPP to the
surveying market.

With integrated state-of-the-art technology, the APS-3L

combines high performance and flexibility. When out of range SPECIFICATIONS
of UHF radios or cellular networks, the APS-3L seamlessly
transitions to L-Band corrections for a sub-decimeter level PPP.

The Altus APS-3L allows Septentrio open architecture

philosophy; the user has the choice of data collector software
from MicroSurvey FIELDGenius or Carlson SurvCE to custom
software tools.

Note: The TERRASTAR L-Band correction service requires a

subscription. This service is for land operations only.
