Why are there two areas of GPS jamming near San Antonio, Texas USA?
Ars Tech has "Why was there GPS jamming for 2 days in Dallas", From October, but your tool shows multiple consistent spots of Interference at San Antonio going back MONTHS and MONTHS

And I see it in a previous HN post, but no answers, just "Military".

EDIT: The Ars Technica article is about GPS Interference of Dallas, to the north. It has in image showing a LARGE swath of "Medium" interference between San Antonio and Dallas, in October 2022.
Your tool now shows ZERO Interference for October 2022.
EDIT: I guess that Randolph Airforce Base has two Military Operating Zones, is the explanation for why these two areas
have been under GPS Interference for all of 2022. The October thing in Dallas is still bizarre, and maybe the US military had one these GPS jammers on the Mexico border as in the article?

- jjwiseman 4y agoRandolph Air Force Base. You’ll see that the interference is associated with Randolph MOAs (military operating areas) and stops on weekends :) Testing and/or training.
- nullish_signal 4y agoNot Plausible. Randolph Air Force base appears to be Northeast of San Antonio. The -two bubbles- of Medium interference are on Highways to the -West- and -Southeast- of the city. EDIT: Yea, that Weather Map does show big "MOA"s nearby. I guess it was silly to assume MOAS would be nearer Dallas, Texas, as the MOAS are really further from the capitol city. Here's the two Interference bubbles near San Antonio https://gpsjam.org/?lat=29.17662&lon=-98.43553&z=8.4&date=2022-12-22 https://gpsjam.org/?lat=29.17662&lon=-98.43553&z=8.4&date=20...
- jjwiseman 4y agoTwo things: 1. gpsjam.org has useful permalinks. Copy and paste one here and I can see exactly what you’re talking about. 2. You’ve described exactly where some Randolph MOAs are. It makes me wonder if you looked at a map before claiming my explanation wasn’t plausible.

- nullish_signal 4y agoYea, I just saw the Air Base off in a direction I did not recognize as "approaching Dallas", and assumed any used space would be in the same direction. I went back and edited/ deleted some comments.
- jjwiseman 4y agoIf you want a mystery to solve, the recent jamming around Chengdu is unusual: https://gpsjam.org/?lat=30.54828&lon=104.34787&z=6.6&date=2022-12-22 https://gpsjam.org/?lat=30.54828&lon=104.34787&z=6.6&date=20...
