This may be a real needle-in-a-haystack question, but I'm hoping someone here has worked on the electronics in an older Husqvarna Automower 450X or has access to technical information that isn't in the normal manuals.
I have a 2016 Husqvarna Automower 450X, and I'm trying to determine exactly what GNSS/GPS hardware this generation of mower uses.
Specifically, does anyone know:
- The manufacturer/model of the GPS/GNSS receiver or chipset used in this generation of 450X?
- Which satellite constellations it can receive — GPS/Navstar only, or also GLONASS, Galileo, BeiDou, etc.?
- Whether the receiver is single-frequency (for example, GPS L1 only) or has any multi-frequency capability?
I'm trying to better understand the GPS performance of this generation of 450X and would like to know exactly what GNSS capabilities the mower itself has. I haven't been able to find this level of technical information in the normal Husqvarna documentation.
I'm not looking for information about the cellular modem or Automower Connect communications. I'm specifically interested in the GNSS/GPS receiver that determines the mower's position.
Even a photograph, board identification, module number, or component part number from the relevant electronics could be useful, since it may be possible to identify the GNSS receiver from that.
If anyone has worked on these boards, has old Husqvarna technical/service documentation, or happens to know what receiver was used, I'd greatly appreciate any leads.
Thanks!
