Please see attached tutorial
Important note :
You need to use the RINEX standard.
If you are using T02 file (Trimble binary format), you need to convert it in .??o, .??g, .??n, .??h and/or .??b, where ?? stands for some digits.
For this you can use Trimble utility "ConvertToRinex".
Kindly note that due to software evolution, there might be some differences between tutorial and latest version of Delair After Flight.
