The module currently does not support AT commands.

 Heading refers to the direction of device movement and is unrelated to the inertial navigation unit. Inertial navigation merely calculates position information when signals are obstructed.

 The MS36SN4 supports dual antennas and can provide heading information when stationary or in slow motion, whereas other modules cannot achieve stationary heading output.

Disabling the inertial navigation will certainly reduce power consumption, but the difference in power consumption compared to when it's enabled is not significant, so it doesn't hold much significance.

The statement is incorrect; it only provides directional accuracy for a 1-meter baseline. The closer the baseline, the worse the directional accuracy, and it does not scale proportionally.

The directional information from MS36SN4 is custom data, and there is no standard NMEA sentence for it. The output consists of GPHPR sentences.

We provide active antennas with filtering and attenuation. Standalone ceramic antennas are passive, and we currently do not offer them.

It is not possible. Our module has the following limitations in its application:

1.Dynamic Range < 4g

2.Altitude < 18,000m

3.Velocity < 500m/s"
