Site Navigator is a free field tool for locating GSM BTS towers and telecom base stations across Ireland. It provides fast access to 8,107 Irish GSM sites sourced from ComReg — the Commission for Communications Regulation.
Search any ComReg site number instantly — for example 3647, CE006, or CK044. Results show the site name, county, grid reference, operator, and GPS coordinates. Use the map link to navigate directly to the tower location in Google Maps.
Tap the Nearest button to use your device's GPS and find the closest GSM base stations to your current position. Results are sorted by distance in kilometres and include bearing for field navigation.
All tower and site data is sourced from ComReg's open dataset of licensed telecom infrastructure in Ireland. The database covers GSM base transceiver stations (BTS), mobile network masts, and telecom sites operated by all major Irish network operators.
When viewing a site, Site Navigator shows current weather conditions pulled from Open-Meteo — including temperature, wind speed, and precipitation. Useful for field engineers planning site visits.
Find the nearest fuel stations to any GSM tower site using OpenStreetMap data. Distances and directions are shown for easy field logistics planning.
A BTS (Base Transceiver Station) is a piece of mobile network infrastructure that communicates wirelessly with mobile phones and devices. BTS towers form the backbone of GSM networks. In Ireland, all BTS sites must be registered with ComReg.
Use the GPS Nearest feature in Site Navigator. The app uses your device location to calculate the closest ComReg-registered GSM tower sites within range and lists them by distance.
Tower and site data comes from ComReg's open dataset of Irish telecom infrastructure. Weather data is provided by Open-Meteo (CC BY 4.0). Fuel station data comes from OpenStreetMap contributors under the ODbL licence.
Yes. Site Navigator is a free personal project built for field use by telecom engineers in Ireland. It requires no registration or login.
Location data is sourced directly from ComReg and reflects officially registered site coordinates. Accuracy depends on the precision of ComReg's dataset. Data may be incomplete or outdated in some cases.
Site Navigator is a Progressive Web App (PWA) and can be added to your home screen on Android and iOS. Core functionality including site search works offline after first load. Weather and fuel data require an internet connection.
