Welcome to KeyNet GPS, Inc.

KeyNet GPS is a new business venture of Keystone Precision Instruments. KeyNet GPS is a series of continuously operating, high precision GPS reference stations. These reference stations have all been linked together using Trimble GPSNet software, creating a Virtual Reference Station System (VRS). For a more detailed explanation of a Trimble Virtual Reference Station Network, see Product Summary below. KeyNet GPS sells subscriptions to and provide real-time data to clients using the Internet. The real-time receiver or rover is linked to the Network using wireless Internet technology.

Productivity - There is no need for a base station. If you own a Trimble RTK system, your base station may be able to be used as a second rover, doubling your productivity.

Affordability - With only one GPS receiver required, the cost of equipment survey personnel is reduced significantly.

Accuracy - Instant survey-grade accuracy within the system area.

KeyNet GPS has deployed Trimble's RTKNet Infrastructure software. Designed to provide true Network RTK performance, the Trimble RTKNet software enables high-accuracy positioning in real time across a geographic region. The RTKNet software package uses real-time data streams from the GPSNet system and generates correction models for high-accuracy RTK GPS corrections throughout that network. It is ideal for any application requiring reliable, fast, high precision wide area positioning.

RTKNet provides the highest level of RTK performance achievable from a network of base stations. RTKNet provides all of the same features as GPSNet for reference station configuration, data logging, individual base RTK streams, and 24/7 availability. In addition, by creating a systematic error model across the network, RTKNet provides VRS (Virtual Reference Station) or SAPOS/FKP broadcast RTK corrections, enabling rover users to achieve fast, high-precision performance over much larger areas than standard RTK. It maximizes the achievable RTK performance from a network of reference stations and eliminates the need to set up a temporary field base station for each individual project, saving you time and money.

The Trimble NetR5 Reference Station is a multi-channel, multi-frequency GNSS (Global Navigation Satellite System) receiver designed for use as a stand-alone reference station or as part of a GNSS infrastructure solution. Trimble R-Track technology in the NetR5 receiver supports the modernized GPS L2C and L5 signals as well as GLONASS L1/L2 signals. This extensive GNSS support is capable of providing users with real field benefits. The Trimble NetR5 is rugged and lightweight, and consumes very little power due to its purpose-built ASIC (Application Specific Integrated Circuit) platform. The NetR5 can operate up to 20 hours in tough conditions on a single charge. Collect, store and transfer large amounts of data easily and conveniently via the NetR5 receiver's limitless expandable memory. The receiver supports USB devices such as memory sticks as well as external hard drives.
