Cueing TPOD from A/G Radar (Accuracy)

[Poptart]

Is there anything I need to do to increase the accuracy of the TPOD when cueing it from the A/G radar? In the last mission I did the TPOD was pointed about 10 degrees upward. Almost as if there was a problem determining altitude of the target.

The radar cannot determine the elevation of the target independently from an HRM (SAR) map. It will pull the elevation of the closest steerpoint if you have SP in PB17, or the steerpoint you have in PB17 when you cue the pod or make a designation. If that elevation is off from where you have cued the pod then yes the pod will be pointed significantly above or below the point on the ground you were trying to cue it to.

Only way you can combat this is by understanding this is how it works, and having a steerpoint made relatively near where you are planning on cuing the pod.

Wouldn't INS drift be an issue to not make the TGP cue to the same spot on the Radar?

[KlarSnow]

INS drift would not be an issue because the coordinate system that underlies the radar would generate the same relative cuing command for the pod regardless of drift or lack there of. The pod cues to a relative position that is calculated based on the coordinates the radar provides. If the INS is drifting its the same error in the same direction for both the radar and the pod.

Cuing the pod to an INS set of coordinates (a steerpoint or markpoint) would display a relative error. Since the INS location would be drifting relative to the world IE an outside absolute source.

Thanks for the clarification.
