1 Accuracy and TTFF specifications may be affected by atmospheric conditions, signal multipath, satellite geometry and corrections availability and quality. 2 Performance values assume minimum of five satellites, following the procedures recommended in the product manual. High multi-path areas, high PDOP values and periods of severe atmospheric conditions may degrade performance. 3 Long baselines, long occupations, precise ephemeris used 4 At very low temperatures UHF module should not be used in the transmitter mode. 5 Without batteries. Batteries can be stored up to +70°C. 6 Network RTK PPM values are referenced to the closest physical base station. 7 Receiver initialization time varies based on GNSS constellation health, level of multipath, and proximity to obstructions such as large trees and buildin

Features
UNIQUE 7G GNSS-CENTRIC TECHNOLOGY
Patented Z-Blade processing technology running on a next generation Spectra Geospatial 600-channel 7G ASIC fully utilizes all 6 GNSS systems: GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS and SBAS, in addition to MSS corrections delivered via L-band. Unlike GPS-centric technology which requires a minimum number of GPS satellites for GNSS processing, Z-Blade™ unique GNSScentric capability optimally combines GNSS signals without dependency on any specific GNSS system; this allows SP85 to operate in GPS-only, GLONASS-only, Galileo-only or BeiDou-only mode if needed. In addition, SP85 supports RTCM 3.2 Multiple Signal Messages (MSM), a standardized definition for broadcasting all GNSS signals from space, regardless of their constellation. This protects the surveyor’s investment well into the future by providing superior performance and improved productivity as new signals become available.
SMS AND EMAIL
MESSAGING
SP85 has a unique combination of communication technologies including an integrated 3.5G GSM/UMTS modem, Bluetooth and WiFi connectivity, and optional internal UHF transmit radio, providing unmatched connectivity for the user. The cellular modem may be used for SMS (text message) and e-mail alerts as well as regular Internet or VRS connectivity. SMS (text messages) can be used to monitor and configure the receiver. Likewise, SP85 can use all available RTK correction sources and connect to the Internet from the field using WiFi hotspots, where available. The internal UHF transmit/receive radio allows for quick and easy setup as a local base station. This saves time and increases the surveyor’s efficiency, allowing for more productive workflows.
ANTI-THEFT PROTECTION
A unique anti-theft technology secures the SP85 receiver when installed as a field base station in remote or public areas and can detect if the receiver has been disturbed, moved, or stolen. This technology allows the surveyor to lock the device to a specific location and make it unusable if the device is moved elsewhere. In this case, the SP85 receiver will generate an audio alert and show an alert message on its display. Additionally, a SMS or e-mail will be sent to the surveyor’s mobile phone or computer and provides the receiver’s current coordinates to allow tracking of its position and follow for a quick recovery of the receiver. SP85’s anti-theft technology provides surveyors with remote security and peace of mind.
TRIMBLE RTX CAPABLE
Trimble RTX correction services offer a wide range of accuracy requirements ranging from better than 2 cm accuracies, up to submeter accuracies, without the need of an RTK base station. Trimble RTX is available for the SP85 GNSS receiver via L-band satellite in regions without cellular infrastructure, and also via cellular/IP delivery. The premium service, CenterPoint® RTX is the most accurate satellitedelivered correction service available today. With the SP85 GNSS receiver and a Trimble RTX correction service, achieve high-accuracy positioning nearly anywhere in the world - even in areas without cellular service, providing truly unmatched connectivity in the field.
THE MOST POWERFUL TOOL FOR RELIABLE FIELD USE
The SP85’s rugged housing, created by Spectra Geospatial‘s engineering design lab in France, incorporates a host of practical innovations. Dual hot-swappable batteries can be easily exchanged in the field as a one hand operation for an interruption-free working day, ensuring surveyors remain productive until the job is done. The impact-resistant fiberglass reinforced casing, designed to withstand 2 metre pole drops and waterproof to IP67, ensures that SP85 can handle the toughest outdoor conditions. The patented UHF antenna, set inside the rugged carbon fiber rod, extends the range of RTK radio performance at the same time as armoring protection. The sunlight-readable display offers instant access to key information like the number of satellites, RTK status, battery charge and available memory. With eLevel technology, the user is able to focus in one place when leveling and measuring as well as automatically store measurements when the receiver is level. These powerful design features combine to make SP85 the most capable, most reliable GNSS receiver, backed by a comprehensive standard 2 year warranty.
