Advancements in GNSS surveying technology

RTK and PPP has evolved from using only GPS observations to now using: GLONASS, Galileo, BeiDou and QZSS data. The addition of the more recent constellations has increased the number of satellites observed from 10 to as many as 30-40. New constellations also broadcast measurement signals at new frequencies.

GNSS survey antennas now must support all constellations and signals. Calian offers a broad range of economical high performance antennas multi constellation and multiband antennas, employing its Accutenna®, VeroStar^TM and VeraPhase® technologies.

Precision asset positioning with versatile and efficient GNSS solutions

• More accurate positioning of assets

• Superior performance in urban canyons or high reflection environments since Calian's antennas provide superior multi-path rejection

• Multi-constellation (GPS, GLONASS, Galileo, and BeiDou) coverage to maximize availability of satellite signals

• Range of sizes from very compact to mid-sized to suit most every application

• Low current models to address applications requiring the use of battery powered receivers

Versatile GNSS models: Wide compatibility and enhanced features

• Wide voltage range to work with virtually every receiver on the market

• Models for Iridium™ use

• Strong electrostatic discharge immunity

• Optional pre-filters to enhance out-of-band signal rejection (such as the 700 MHz band)

• Embedded versions to use in your own housing
