It is end of summer so time for some more serious work, regarding the LimeSDR
Some community members already knows that my main goal in Lime
use is not HAM hobby, but project related with SAR Search And Rescue,
in case of people who needs assistance on wide forest or country side with
poor GSM coverage. Trick is to cheat lost GSM unit to start with some TX - after that,
principle of TDOA & FDOA & Multilateration (MLAT), should be used.
Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA)
measurement combination for stationary “targets” obtained by sensors
mounted on mobile platforms, for example on a pair of helicopters or even ultralight planes
and in future possible UAV-s.
Starting from info here:
https://osmocom.org/projects/osmotrx/wiki/LimeSDR
And here:
http://git.osmocom.org/osmo-trx/log/
Reading that, cooperation level between Lime and OsmoTRX must be fair.
The only possible source of trouble may be Lime on-board clock source.
Therefore expecting external add on clock generator.
Like to hear members experience and estimation of feasibility of Lime / OsmoTRX
use with necessary SW & HW add on-s, like LNA, PA, external clock, 5 GHz high speed links
between two sensors and some missing measurement modules within OsmoTRX.
All comments and suggestions are more than welcome
