Bad GPS data being sent to APRS

The issue

Not sure if this is the best place to post, but I'm trying to figure out how to filter out bad GPS data which is being sent out on APRS.

Example Packet:

2023-11-27 09:15:32 EST: [AE5TC-14](https://aprs.fi/?c=raw&limit=&call=AE5TC-14)>APBPQ1,TCPIP*,qAC,T2RDU:!0000.00N/00000.00Wk000/000Truck [email protected] DMR 1148863 [Latitude and longitude are both 0]

Recommendations

• Is there any way to prevent null positions from being sent?
• Does BPQ have the smarts to prevent major position changes from being propagated?

Hardware

Using a cheap Stratux USB GPS for a Raspberry Pi 4, with a MFJ-1270pi hat, and a MMVDVM hat on top of that. The unit is constantly mobile (powered 24/7) so it shouldn't lose GPS positioning lock. The Pi switches wifi AP's from home to vehicle when the vehicle rolls aways from a known wifi AP, so the IP changes.
