This guide covers setup, operation, and troubleshooting for the Trimble SPS985 GNSS Smart Antenna, including battery usage and connectivity.
The Trimble SPS985 GNSS Smart Antenna is a rugged, lightweight unit combining a GNSS antenna, receiver, internal radio, and battery. It is designed for infrastructure and site development applications, serving as an RTK rover or a quick-setup basestation. The device features LED indicators for satellite tracking, radio reception, data logging, Wi-Fi, and power status, along with Bluetooth technology for cable-free communications.
| Battery Type | Lithium-ion |
|---|---|
| Power Duration (Rx Radio) | about 4 hours |
| Power Duration (Tx Radio) | about 3.5 hours |
The internal battery typically provides about 4 hours of power using the receive radio and about 3.5 hours operating as a basestation using the transmit radio.
The device can be used for layout of structure foundations, earthworks and finishing stakeout operations, initial site measurements to verify design levels, vehicular-mounted site supervisor applications, and measurements or grade/thickness checks on laid materials.
The internal battery provides about 4 hours of power when using the internal receive radio and about 3.5 hours when operating as a base station using the internal transmit radio.
You must charge the battery completely before using it, and if it has been stored for longer than three months, you should also charge it before use.
