Best GPS Devices for Collecting Project Coordinates in Nigeria. In line with the Federal Government’s mandate that all MDAs must submit GPS coordinates for capital projects over ₦150 million, choosing the right GPS tool is now a compliance issue. But not all GPS devices offer the same level of accuracy. Here’s a breakdown of the different types of GPS receivers used in surveying, along with their accuracies and specifications.
1. Mobile Phone GPS (for awareness) Most smartphones have GPS chips, but they are not acceptable for professional projects. They are used generally for awareness. They are ideal for location sharing and general navigation.
Accuracy: 5 – 20 meters
2. Handheld GPS Devices These are entry-level GPS units, mostly used for rough location marking. They are ideal for Reconnaissance surveys, hiking trails, and environmental mapping, but not suitable for engineering or cadastral work.
Examples: Garmin eTrex 32x, Garmin GPSMAP 64sx, Wangan Handheld GPS
Accuracy: Usually 3m
Price Range: ₦300,000 – ₦1,200,000
Limitations: No correction system; subject to errors from satellite geometry, signal obstruction, and atmospheric conditions.
3. Mapping-Grade GNSS Receivers Better than handhelds, these offer improved performance for general mapping tasks. They are ideal for utility mapping, forestry, and general GIS data collection
Examples: SinoGNSS P6H, SinoGNSSP8 RTK Tablet by Comnav Technology.
Accuracy: 0.5 – 1 meter
Price Range: ₦800,000 – ₦1.5 million
Limitations: They work only with CORS.
4. Survey-Grade GNSS Receivers (RTK-enabled) This is the industry standard for any capital project that demands high positional accuracy. They are ideal for Engineering Surveys, Road Design, Cadastral, Bathymetry etc.
Examples: SinoGNSS N3,SinoGNSS Mars, Laser RTK Jupiter, Laser RTK Gintec G40, SinoGNSS N2
Accuracy: 1 – 2 cm (RTK), 5 cm (PPK)
Price Range: ₦3.5 million – ₦9 million depending on brand, configuration, and features
Strength: Uses CORS or base-rover RTK for real-time corrections.
