4.2Configuring ALIGN with SPAN-IGM

Before configuring the ALIGN solution, the SPAN-IGM and the secondary receiver MUST both be powered on and connected directly between COM 2 of the SPAN-IGM and COM 2 of the secondary receiver through either a null modem cable or an appropriate radio connection.

The rover receiver must be an ALIGN-capable model, such as D2S-Z00-000, running the latest OEM6 firmware version.

To enable the dual-antenna ALIGN solution to aid the INS alignment and provide heading updates, the offset between the antennas and the SPAN-IGM must be known. This is achieved by entering lever arms to both antennas, using the SETIMUTOANTOFFSET and SETIMUTOANTOFFSET2 commands.

To configure SPAN with ALIGN Aiding:

1.Enter the lever arm from the SPAN-IGM to the primary antenna (primary antenna is connected to the SPAN-IGM) using the SETIMUTOANTOFFSET command.
