GNSS Receiver Firmware Options

Proprietary card level programs that help customize your receiver's performance for unique application requirements.


Space available on-board the receiver for a user application separate from the main receiver firmware


Provides high precision attitude and accurate relative positioning information between two or more receivers in dynamic land, air and marine applications


Smoothing algorithm for repeatable pass-to-pass accuracy


Network Transport of RTCM via Internet Protocol (NTRIP) is an application level protocol used to stream GNSS differential correction data over the Internet


Receiver Autonomous Integrity Monitoring (RAIM) firmware provides receiver autonomous integrity monitoring for broadcast GNSS signals by detecting and excluding faulty signals that may cause positioning instability

SPAN® Heave

Eliminates vertical wave motion from sonar data measurements in marine applications

SPAN® Relative INS

Relative position, velocity and attitude solution


STEADYLINE technology reduces position jumps that can occur when a GNSS receiver changes positioning modes

SPAN® Land Vehicle

Optimizes SPAN performance in fixed wheel land vehicle applications

SPAN® Rail Profile

Optimizes SPAN performance in rail applications.

SPAN® Marine Profile
