The “p3k” stands for Paradise PPK is positioning module to deliver centimeter-level accuracies in seconds for the precise navigation and robotics markets(UAV mapping). The main features are: high precision GNSS module, delivers centimeter level accuracy in seconds, fast convergence times, plug and play, Anti-jamming, Anti-spoofing, The time and coordinates of each photo are logged with a resolution of less than a microsecond. This method allows GCPs to be used only to check your accuracy. After the flight, get the RINEX logs from your airborne module and a base station
