So a lot of phones seem to support this and with assistance data could
maybe provide a location.
Did you try to correlate IMEI manufacturer part with the messages ?
No, not yet.
Do you have any log of a successful response ? Maybe I
screw up the
encoding of the position somehow.
Yes, here is an example. This is the response from the phone
42 11 00 00 6A 57 9F B6 41 29 B1 B0 10 8D 84 00 6C 9C 9C 01 B1 0C
This is decoded PDU (asn1c was used):
PDU ::= {
referenceNumber: 2
component: MsrPosition-Rsp ::= {
locationInfo: LocationInfo ::= {
refFrame: 0
gpsTOW: 6969247
fixType: 1
posEstimate: 90 4A 6C 6C 04 23 61 00 1B 27 27 00 6C 43
}
}
}
And those are the coordinates from "posEstimate" (I did not care about
the height):
52.329040 - 52 19'44" N
5.819342 - 5 49' 9" E
Best regards,
Dieter
