That is dastardly cool Bryan. Yeah, the GPS is likely only good to find the
rocket. To use GPS on record flight attempts one has to use an approved unit
by the governing body.Good luck. Kurt KC9LDH

Hi Andrew-
Yeah, I know I don’t need one for the record. I used an EasyMini for the
I-record I recently set. The GPS is just to help find the rocket. I can fox
hunt, but it’d be a lot easier to just trek to the lat/long. The GPS I used
with my I-record flight only weighs about 6 grams, but it doesn’t have a
telemetry radio built in. If I can grab a spare input serial port on the STM32,
it’d be ready to have the TeleMini send the coordinates to the ground.
I’ll get to those 30k+ records that require a GPS later! :)
Thanks,-Bryan

Hi Bryan,
I'm the guy who recommended you post here. Given you're going for a G-motor
record you altitude will be limited and therefore I don't believe you actually
need GPS for the record. Baro will be fine for the altitude you G motor record
rocket will reach.
I'm all for you integrating a GPS chipset to the TeleMini but I thought the
above would be worth mentioning in case you were under the impression that
you'd require a GPS fix to claim the G motor record.
Regards,
Andrew H.

Hi everybody. I posted on the Facebook group, but someone there suggested I try
the mailing list instead…
I’m putting a TeleMini in a nosecone for a 24mm rocket that I’m hoping to break
the TRA G-motor record with. There isn’t enough room in the nosecone for
anything bigger than the TeleMini, but it looks like there will be just enough
room for a separate little GPS. Is there a way to feed the TeleMini a NMEA
stream & have it send GPS coordinates over its telemetry? It looks like several
of the STM32's pins are accessible....I'm ok writing some code to make it
happen.
Thanks,-Bryan
