Intellishoot L1L2 PPK Geotagging System
The Intellishoot Geotagging system, built by Event 38 and powered by the Piski Multi, is a stand-alone unit designed to be easily integrated into any system that requires high accuracy and high reliability image positioning. The system includes a dual frequency receiver, antenna, and PPK geotagging software.
Powered by the Piski Multi GNSS core, the device currently accepts GPS/GLONASS (L1/L2,G1/G2) frequencies and is hardware ready to add BeiDou and Galileo (B1/B2, E1/E5b)and SBAS via firmware update. To integrate with your aircraft, the device needs only power supplied between 9-32V and a 3.3V pulse from your camera. Logs are recorded automatically onto a USB stick for easy retrieval. The logs can be processed against any base station that produces raw observation files in Rinex format, including CORS and VRS stations.
The intellishoot L1L2 PPK Geotagging System is capable of producing extremely accurate geotags for cameras integrated onto a UAS or light aircraft. In our case study, we demonstrated horizontal and vertical RMSE of 2.82 and 3.62cm respectively from 100m AGL flying height and ar 12m/s flying speed. Producing orthomosaics and DSMs with such accuracy and without the need to collect ground control points significantly increases the efficiency of survey missions, even for relatively small and easy to access areas.

The Intellishoot System can be integrated with any autopilot system and any camera capable of providing a high precision shutter timing signal. The camera can be triggered by its normal integrations with the autopilot, making the system more easily compatible with a wide variety of cameras. Intellishoot needs only a power source, a shutter exposure signal, and a place to mount the antenna. Event 38 can answer questions and provide support for integraation with your system.

Dual Frequency vs L1 Only
The primary advantages of working with a dual frequency setup are a faster time to fix, more reliable fix holding, and single solution post-processing. By using two frequencies from each satellite, dual frequency receivers are able to more quickly determine ionospheric conditions and calculate a high accuracy fix faster. This also allows them to recover from a loss of fix and pick up new satellites as they come into view more quickly. With single frequency PPK, there can be multiple solutions produced when post-processing the GPS data. This means that the solution can be affected by, for example, where in the GPS string you clip the data to start and stop processing, L1L2 produces only a single solution, making post-processing easier and more consistent, The accuracy produced by an L1L2 system in good conditions is typically not higher than with an L1-only system. However, in marginal conditions where a solution may be intermittently lost, L1L2 is better at maintaining solutions for longer and re-acquiring them more quickly when lost.
