intelfx Posted January 8, 2022 Report Posted January 8, 2022 (edited) After completing the flight compartment checklist, the GPS subsystem appears to be stuck in a weird state with debug screens not working and nothing apparently happening. Edited January 8, 2022 by skiselkov
Graeme_77 Posted January 8, 2022 Report Posted January 8, 2022 Hello Intelfx, sorry you're having this issue with the product. It's not something seen at all testing. Does the sim computer have access to the internet? The GPS almanac is downloaded when the avionics power up.
Huang JL Posted January 8, 2022 Report Posted January 8, 2022 I have the same problem GNSS NOT AVAILABLE
intelfx Posted January 8, 2022 Author Report Posted January 8, 2022 Yes, it is connected to the Internet. And indeed, that seems to be the problem: 2022-01-08 08:49:57 CL650[alm.c:151]: Unable to download GPS almanac from https://navcen.uscg.gov/?pageName=currentAlmanac&format=sem: Couldn't resolve host name

skiselkov Posted January 8, 2022 Report Posted January 8, 2022 Please be sure to enable a VPN on your computer. The aircraft needs to talk to https://navcen.uscg.gov to download a GPS almanac - this is needed to simulate GPS satellite positions. 1 1
2Fat2Fly Posted January 8, 2022 Report Posted January 8, 2022 (edited) Same issue here. Without GPS the aircraft basically can't go anywhere as it loses RNP APCH capabilities, etc.. IMO simulation of the essential systems should not rely so heavily on Internet access. There should be alternative approaches to them when the Internet one is not available.

George Wu Posted January 8, 2022 Report Posted January 8, 2022 Is it possible for the dev to provide a local copy of the GPS almanac data when we download the aircraft? The data doesn't need to be the latest one. just an option for players who don't have Internet access or are geo-restricted in their area. For me personally, I often take my laptop to places that don't have Internet, and I'd like to be able to fly it even I'm offline.

Expand I understand this situation, so is there a way to simulate a GNSS system without using the GPS almanac data? like any other aircraft that uses native x-plane nav data. GNSS is a core system on this aircraft. I want to know if there is a way to make this system work.(without breaking the law of course). Thank you for the reply. Edited January 8, 2022 by George Wu

Once you have the file locally you can e.g. do subsequent flights offline and still have GNSS?
Graeme_77 Posted January 8, 2022 Report Posted January 8, 2022 Yes once it has an almanac downloaded it will keep it until it can replace it. 1

Expand If you can't guarantee all essential functionality in the distributed package, you should issue a warning like "access to navcen.uscg.gov is mandatory, otherwise the GPS on this aircraft won't work" on the store page, or offer a refund for those who can't use the aircraft properlly due to this issue. The situation is, 1. customers would expect a product with full advertised functionality because they are not warned about some of them will not work if access to unspecified, unrelated domain were blocked and of the X-Aviation no-refund policy, and 2. customers could not legally acquire the said almanac files in this case either. I hope there will be an offline solution for this, like simulating GPS position without the said, close-to-reality almanac. It is OK to have a less accurate model here as the more accurate one is not achievable. 2
Rodeo Posted January 9, 2022 Report Posted January 9, 2022 Maybe the plugin could know both the URL and static IP for the server, and try the IP as a fallback if the URL is not reachable?
2Fat2Fly Posted January 13, 2022 Report Posted January 13, 2022 Hi everyone, Accroding to the post in the Discord server, this issue will be fixed in the next update: Thank you Hot Start team for the quick fix for this issue! You guys rock for creating the most state-of-the-art aircraft ever in the X-Plane history!
eddinator Posted January 17, 2022 Report Posted January 17, 2022 I have a similar issue, but only with my GPS 1 (looks exactly like the study panel from the screenshot in the first post), the GPS 2 is working as expected. The issue oocured just today. I did a quite a couple of flights before and haven't had that issue. Any suggestions on that? Many thanks!
