In order to speed up the GNSS synchronisation, tapping GNSS “Searching…” string will force the BLIP
to download the GNSS almanac information over LTE. This LTE download will take approximately 90
seconds to complete. Once this download has been done the GNSS synchronisation process will
proceed much faster.

BLIP in Tracking mode – ready for flight
The app’s “Start Flight” button is only active when:
• The operator’s registration ID is manually entered by tapping the underlined text:
• Operator Registration ID: is “NULL” by default. The format needs to be EASA regulation compliant e.g.
FIN87astrdge12k-xyz-8:
▪ FIN is the ISO 3166 Alpha-3 country code for Finland in this example
▪ 87astrdge12k is the CAA generated 12 characters random string
▪ xyz is the CAA generated 3 characters random string (not displayed nor broadcasted)
▪ 8 is the Luhn mod-N checksum on the 12 and 3 characters random strings
• Entering an invalid registration ID will result in the BLIP displaying/broadcasting “NULL” as registration
ID.
• The unique serial number complies with the ANSI/CTA-2063 formatting rules concatenating a 4
character alphanumerical manufacturer code (UFLY for Unifly) and the unique Bluetooth MAC
address.
