IS GPX-1
The IMX can be configured for use with the Inertial Sense GPX-1 multi-band GNSS receivers. This can be done using either the EvalTool GPS Setting tab or the IMX DID_FLASH_CONFIG.ioConfig and DID_FLASH_CONFIG.RTKCfgBits fields.
| GPS Ports | Value |
|---|---|
| GPS Source | serial 0, serial 1, or serial 2 |
| GPS Type | GPX-1 |
| GPS1 Timepulse | Disable or IMX pin connected to GPX-1 |

The following sections detail how to interface and configure the IMX for operation using the GPX-1. See RTK precision positioning and RTK compassing for RTK operation principles.
Typical Interface¶
The IMX will automatically configure the GPX-1 for communications.
Rugged-4 (Coming Soon)¶
The Rugged-4 INS contains the GPX-1 onboard supporting RTK positioning and compassing. GPS 1 and GPS 2 are connected to serial port 0 on the IMX-5.
