Light APRS+WSPR Tracker: ublox_high_alt_mode_enabled = false

I have a Light APRS+WSPR tracker intended to be used on a pico balloon that will float higher than 12,000m. I am curious about this variable in the source code:
ublox_high_alt_mode_enabled = false (which in one case in the code is set to true) I am not clear on what this does. I read in one case that it means you cannot track altitude above 12,000m unless it is turned on. Is this true? Do I need to make any changes to the default sketch on github to ensure i can track from ground level to >12,000m? Thx. Adrian VE7NZ |

Hi Adrian, It's a temp variable. Do not change it. High altitude mode is not permanent. During sleep (low power mode) GPS is off and back to standard mode.  When the GPS is on again, this variable is checked, if it's false, high altitude mode is enabled again.

Thx. I am in the industry and have some work related activity with u-blox, yet I do not know what "High altitude mode" is. Can someone enlighten me? Thx. Adrian.

Hi Adrian, Ublox modules have multiple modes (dynamic platform models). See the following table. For more detailed info, check out Receiver Description Document : https://content.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_UBX-13003221.pdf  On Thu, Mar 23, 2023 at 12:07 AM ve7nz <adrian@...> wrote: Thx.
