NavCom Technology Inc.

RTK Meets StarFire-a revolutionary solution to RTK communication drop-outs
An industry first from NavCom, RTK Extend enables continuous RTK position accuracy during radio communication outages by utilizing NavCom's global StarFire corrections. Traditionally, when an RTK rover loses communication with the base station, it is unable to provide position updates for more than a few seconds, resulting in user downtime and reduced productivity. With RTK Extend, a StarFire series receiver with RTK enabled maintains the RTK accuracy for up to 15 minutes of communication loss, allowing for optimal work efficiency in the field, without communication interruptions.

Satel

Free Channel Scanning
SATELLINE-3AS is a half-duplex radio modem suitable for a variety of data transfer applications, particularly ones demanding high speed and precision. Free Channel Scan (FCS) is a new feature for the SATELLINE-3AS family. It is designed for one-way transmission between one transmitter and one or more receivers when there are at least two different transmission frequencies available. The transmitter monitors the noise level of the channels between the transmissions and finds the best transmission channel. This feature is beneficial especially when license free channels are used and there could be other transmitters using the same channels.

Pacific Crest Corporation

Positioning Data Links
Surveyors using GPS and Real-Time Kinematic (RTK) technology require a rugged radio data link for precise positioning information. Pacific Crest Positioning Data Links (PDL) are compact and lightweight radio modem rovers and base stations, available in low-power (.5W and 2W) and high-power (35W) options. With advanced features such as 19,200 baud over-the-air data rate and enhanced user interface that enables the surveyor to change channels and other settings on the unit with the touch of a button, PDL radios are easy-to-use, and provide high performance and rugged dependability for the toughest environments. Pacific Crest PDL products are compatible with all surveying equipment and designed to easily mount on standard tripods and range poles.

SOKKIA

SOKKIA's Axis3 L1 DGPS system is now available with a Bluetooth adaptor for convenient wireless communication. The adaptor eliminates the need for a cable between the receiver and data collector. The 12-channel, L1 DGPS receiver also offers three types of real-time corrections (Beacon, L-band and WAAS) for reliable and accurate positioning.

Stratus is SOKKIA's L1 Integrated GPS system offering completely cable-free operation. It features internal batteries, an internal antenna and infrared (IR) communication with the user's data collection device. Stratus is the lightweight, rugged, cable-free choice for static and kinematic surveying projects.

Thales Navigation

The Z-Max GPS surveying system from Thales Navigation features a unique combination of wireless communication devices. The modular design of Z-Max enables a completely wireless RTK rover using Bluetooth, GSM and UHF technology. Thales Navigation-developed UHF radio technology means optimum tuning for the Z-Max receiver and, therefore, excellent performance and long-range capability even with low power outputs. The new Vortex UHF antenna eliminates conventional radio antennas and cables. The combination of UHF and GSM in one single communication module lets surveyors achieve long ranges quickly and cost effectively. It also provides maximum flexibility for all environmental conditions. Z-Max's long range RTK is enhanced by ADAPT-RTK technology, which provides fast initialization and centimeter-level accuracy up to 50 km.
