Procyon 100
The Procyon 100 range lets you collect geospatial coordinates at an accuracy of 15metres, increasing to 1-3metres when SBAS satellites are available.
The Procyon 100 range is a GPS enabled device with the ability to receive satellite-based augmentation system (known as SBAS) corrections thus providing the capability to fix to ~15m, increasing to 1-3m when SBAS satellites are visible. This level of accuracy is suitable for geo-tagging images, locating building and outdoor navigation.

Procyon 200
The Procyon 200 range lets you collect geospatial coordinates at an accuracy of 70-100cm.
The Procyon 200 is a device which features improved electronics and software enabling the greater resolution of 70-100cm. This is whilst still using only standard GPS signals with satellite-based augmentation system corrections. This provides fixes when standard GPS accuracy is not sufficient for locating smaller objects like street furniture.

Procyon 300
The Procyon 300 range lets you collect geospatial coordinates at an accuracy of 30-50cm.
The Procyon 300 is a highly accurate GPS enabled device providing 30-50cm using only the GPS L1 frequency with a differential GPS correctional service. This service has increased availability over the satellite-based augmentation correctional service, making which is important when accuracy is essential at all times. The device is field upgradable with a software update to the Procyon 400.

Procyon 400
The Procyon 400 range lets you collect geospatial coordinates at an accuracy of 1-2cm.
Finally, you have the Procyon 400, the top of the range product providing survey grade precision accuracy of 1-2cm by using dual constellation GPS and GLONASS L1/L2 frequencies augmented with a real time kinematics (RTK) correctional service. The dual constellation improves the availability of satellites and reduces the frequency of non-ideal satellite positions which could cause reduced accuracy when using a signal constellation system. This device is recommended for users requiring the most precise measurements available such as when producing survey maps.
