Description
#GPK2
The Seagull #GPK2 is a professional-grade dual-band GNSS receiver engineered for demanding aerial and land-based applications that require extremely accurate positioning data. Built on advanced GNSS technology, the #GPK2 offers multi-frequency support, delivering significantly faster satellite lock times, improved signal integrity, and centimeter-level accuracy—making it a powerful asset for mapping, surveying, georeferencing, and precision agriculture.
The following satellite signals can be tracked and decoded by the receiver: GPS L1C/A – L2C, GLONASS L1OF – L2OF, GALILEO E1-B/C – E5b, and BEIDOU B1I – B2I.GPK2 modules can function in Real Time Kinematic, Post Processed Kinematic, and Moving Baseline modes, respectively, as ROVER or BASE.
The modules enable LATITUDE, LONGITUDE, and ALTITUDE format internal data logging of RAW data for post-processing. The onboard EVENT PIN of #GPK2 allows for the exact logging of coordinates depending on feedback from the camera shutter or other sources. Shop now on XBOOM.
