Shahin Geospatial uses high-precision GNSS receiver that supports all major global satellite navigation systems, providing real-time differential corrections that generate centimeter-level positioning data. We work in challenging conditions where Centimeter accuracy can be achieved on distances up to 60 km in RTK, and 100 km in PPK mode.
We process RINEX raw data logs which are compatible with PPP services so we can now get centimeter-precise results in any place on Earth. We process RINEX files in an online service and get position with absolute accuracy.
RTK GCP Acquistion
RTK technology that provides real-time, centimeter-level positions. We're using highly accurate GNSS system. We provide GCP fly through service form national benchmark towards the project area. Our work based on the requirement are laying of multiple GCPS/ NTRIP/ CORS/PPP Services. A permanent GCP monuments/ artificial structure can be constructed for all of surveying fieldwork needs.
Single Receiver Precise Positioning
If you have only base station but no rover, we process the single receiver to achieve high-level accuracy without the use of corrections from the base station. To calculate the coordinates, we use the same data that is provided by the navigation message but much more accurate. Thereby, the Single receiver might determine its position with a centimeter-level accuracy using only its own raw data and precise ephemerides and clock offsets provided by a our processing service.
GPS Post Processing (Base-Rover)
Post-Processed Kinematic (PPK) is an alternative technique to Real-Time Kinematic (RTK). With PPK workflow, accurate positioning doesn't happen in real time, all algorithms are applied afterwards. Both base on the ground and rover (usually on a UAV) record raw GNSS logs, which are then processed to receive an accurate positioning track. While PPK is mainly used in UAV mapping, it can also be used as a back up for RTK for any surveying job. Our PPK processing offers more hassle free flexible workflow, allowing to run the processing multiple times using different settings. It also doesn't require a correction link between base and rover.
Point Staking
Staking out an important part of construction projects. When classical terrestrial surveying methods are used in staking out of construction projects one can meet with some difficulties such as lack of sight between two control points, inaccessible angle points and loss of time. Here we provides RTK GPS surveying where our method has some advantages over classical geodetic surveying methods in that RTK GPS does not need sight between control points., RTK GPS surveying method offers fast and precise positioning in staking out process. We import drawings to our RTK system and find stake the exact real-world positions
