Machine control technology boosting efficiency

Hemisphere says that its new S321+ and C321+ GNSS smart antennae are well-suited to mounting on construction equipment to offer machine control technology. The multi-frequency S321+ and C321+ systems offer Athena RTK and Atlas GNSS global corrections and are upgrades to their previous versions. The new units have additional capabilities and are powered by the Eclipse P326 OEM board, supporting 394 channels. These can simultaneously track all satellite signals including GPS, GLONASS, BeiDou, Galileo, and QZS

Hemisphere says that its new S321+ and C321+ GNSS smart antennae are well-suited to mounting on construction equipment to offer machine control technology. The multi-frequency S321+ and C321+ systems offer Athena RTK and 7985 Atlas GNSS global corrections and are upgrades to their previous versions. The new units have additional capabilities and are powered by the Eclipse P326 OEM board, supporting 394 channels. These can simultaneously track all satellite signals including GPS, GLONASS, BeiDou, Galileo, and QZSS, as well as being robust and reliable. The S321+ and C321+ combine Hemisphere’s Athena GNSS engine and Atlas L-band correction technologies with a new webUI.


The rugged antennae are designed for use in challenging environments and come in two versions, with 4G LTE optimised for either North American or international locations. The S321+ and C321+ are preconfigured to test-drive corrections from Hemisphere’s Atlas L-band correction service. The bundled solution provides users worldwide with an easy way to use Atlas, including Hemisphere’s Atlas H10 service offering 8cm 95% accuracy. They also use Hemisphere’s aRTK technology, powered by Atlas, which allows the receivers to operate with RTK accuracies when RTK corrections fail.

    Versatility and productivity are key drivers for the concrete plant sector - Mike Woof writes. The days of most construction machines being expressly designed and built for a single specific purpose have gone. These days construction equipment is largely intended to be versatile and adaptable, allowing it to be operated in a wide array of applications and duties. New concrete plants are designed too for mobility as this allows users to set up highly productive equipment quickly on basic sites, with little p

    Machine control technologies were pioneered in the concrete paving sector with systems having been used for over 10 years. Leica Geosystems was the first of the machine control technology suppliers to offer these systems on concrete slipforming machines and has developed a strong position in this segment. However the company met resistance from some quarters in the construction market and specialist Karl Soar said that some contractors were very reluctant to give up using conventional stringlines.
