Not sure if the ephemeris is sent from the phone/tablet connected to the internet to the internal gps chip of the Anafi...
Most of the time my tablet is not connected to the internet when on the field (no SIM card in the iPad, WiFi signal far away, and airplane mode).
But your theory about ephemeris could be in fact the following :
- The Anafi internal GPS does auto-build its map of existing satellites without the need of the internet.
- when you use it regularly, the ephemeris does auto-update depending on the signal it received from USA GPS and Russian Glonass. The cycles of the CPU allows this update.
- There is an update on the Anafi line of product with a newcomer ‘The Anafi USA’ that needs to connect to more GPS constellations than the regular Anafi.
- This Anafi USA has a lot in common with the regular Anafi except some components that are made in the USA (probably a CPU) and can keep some critic components that are not made in China (the GPS chip is from Ublox a Swiss company)
- The whole range of Anafi, including our good old bird, benefits from this update and its GPS after the update Can catch 3 constellations (let’s add the European Galileo GPS satellites for example, that would explain the increase in GPS we catch since the last update).
- If all the above is realistic, then our old Anafi CPU cycle and its software may not be able to compute such informations as fast as the Anafi USA. What is also documented by ublox is the fact their GPS chip is much slower when you use 3 constellations rather than 2.
- Add to that the ephemeris must be ‘home build’ for 3 constellations of satellites instead of 2...
I wouldn’t be surprised if a soon to come update would revert to the original 2 constellations caught by our Anafis... keeping the 3 for the Anafi USA...
Let’s wait and see...
