There is no national unified CORS differential network in rural Nigeria, and 4G is completely missing in remote villages; The southern tropical rain forest is covered by tall shrubs; High temperature and humidity in rainy season, and large amount of red soil and sand dust; Local operators only master English and have weak professional ability; The number of government authorized projects is huge and the budget is limited.
Project overview

The land ownership confirmation project funded by the World Bank covers 28 villages and towns, with a total of 4600 residential bases and farmland ownership plots. There are dense wild rainforests, and the daytime maximum temperature is 45 ℃, without a stable mobile network.

TK-800 base station delivers 8km UHF coverage with 4G-independent differential output. 1408 full-constellation channels resist tree occlusion and ensure drift-free long-term fixation. It supports DJI drone aerial survey for orthophoto mapping.

Four teams adopt TK-600 rovers for boundary collection. 60° tilt measurement enables fast survey without pole leveling. Multi-language voice broadcast simplifies operation for local workers.
TK-600 provides expandable TF storage and diverse radio protocols, supporting compatibility with other-brand GNSS devices for collaborative surveying.
