SPAN Installation

This chapter contains instructions and tips to setup your SPAN-IGM system.

2.1Required Equipment

A SPAN-IGM integrated GNSS + INS receiver

A quality, dual frequency GNSS antenna such as the GPS-702-GG or ANT-A72GA-TW-N for airborne/high speed applications. See the NovAtel website (www.novatel.com/products/gnss- antennas/) for information on a variety of quality antennas available to meet your form factor and performance needs.

An antenna cable with a TNC male connector at the receiver end, such as NovAtel’s GPS-C016 model

A power supply of +10 to +30 V DC with a maximum typical current of 0.4 A For an ALIGN variant with a FlexPak6, the maximum typical current is 0.65 A

Interface cables for the MAIN and AUX ports on the SPAN-IGM

The interface cables can be NovAtel cables (see SPAN-IGM Cables on page 15) or custom built cables (see Appendix A, Technical Specifications on page 52 for the MAIN and AUX port pin outs).

A Windows® based computer with a USB or serial port

A radio link (if your application requires real time differential operation

2.2SPAN-IGM Hardware

The SPAN-IGM contains an OEM615 GNSS receiver and an IMU containing 3 accelerometers and 3 gyroscopes. The connectors available on the SPAN-IGM are shown in Figure 2, SPAN-IGM.
