PPP-RTK & Open Standards Symposium

Participants of the PPP-RTK & Open Standards Symposium. Unlike conventional differential GNSS methods, Precise Point Positioning (PPP) does not (directly) utilise nearby reference receiver measurements. When performed on GNSS-equipped mobile phones and CarNav systems, PPP uses carrier phase measurements instead of pseudoranges and very accurate satellite orbit and clock data in place of the information in the broadcast navigation message. While PPP has many advantages, one of its critical shortcomings is the lengthy period for carrier phase ambiguity resolution. However, its supporters claim that it will very soon be possible to have reliable sub-decimetre accuracy, real-time positioning, anywhere in the... (read more)

Low-cost Feature-rich RTK Receiver

SkyTraq Technology, a Taiwanese GNSS positioning technology company, has introduced S2525F8-RTK, a low-cost, low-power, single-frequency RTK receiver for applications requiring centimetre-level accuracy positioning. The multi-constellation GNSS RTK receiver can use 12 GPS, eight SBAS and six BDS signals and one QZSS signal. In situations where RTK fix is not possible, a Float RTK mode can be used for decimetre-level accuracy positioning. A moving-base mode is also supported for precise heading GPS compass application. Its 25mm x 25mm form factor, 3 gram weight and 250mW power consumption makes it ideal for any outdoor mobile applications requiring high-precision RTK positioning. S2525F8-RTK supports both base station and... (read more)

North Country Surveyors Warm-up to RTK

Along the border between extreme northern Maine and western New Brunswick, Canada, two surveyors, one Canadian and one American, have found a way to survey in the region's challenging conditions: using RTK. Faced with fewer control monuments, many lying beneath a cover of snow much of the year, limited cell-phone coverage; rugged terrain and UHF transmission limitations - the two men were led to the Ashtech Professional ProMark 500 RTK solution. Michael Cyr, owner of Northern Maine Surveyors in Madawaska, ME, USA, works across the St. John River border from Gaetan Soucy, proprietor of Arpentages Gaetan Soucy. Both are in... (read more)
