Jersey uses it’s own coordinate system and is not covered by the SmartNet RTK Service provided by Leica! DGPS equipment brought over from the UK for conducting surveys in Jersey will not work correctly.
The Jersey GDS Differential GPS Base Station has now been established and is transmitting differential corrections for use by subscribers of the service. The Government of Jersey operate the Differential GPS service for the benefit of local architects, surveyors and utility companies. Initially the service is aimed at users whose requirements are primarily for positional accuracy, with up to 1cm accuracy achievable, but where Height accuracy is not critical to them. Once the Government of Jersey Differential GPS Base Station is moved to its new site, which is expected take place later this year, the optimal Height accuracy achievable with the Zeno 20 will be improved to +/- 2cm.
Differential GPS Equipment Hire
Leica Geosystems DGPS Zeno 20
Digimap are pleased to announce the launch of their new hire service for differential GPS equipment in Jersey. Digimap now have available for hire a Leica Zeno 20, fully configured for the Government of Jersey Differential GPS correction service and ready to go.
As the Zeno 20 is so easy to use, within just 10 minutes of training you can be ready to go onsite and record locations of assets to an optimal horizontal accuracy of +/- 1cm. The Zeno 20 incorporates the latest GPS technology, making it quicker to get a lock on both the GPS and GLONAS Satellites, saving you time onsite.
A typical scenario could be a utility asset surveyor, collecting position and attribute data of services uncovered in a trial trench. Using the Leica Zeno 20 DGPS system the surveyor would: Collect the position, orientation, depth, and details of the services found directly into the device, not have to make a sketch of the locality and note coordinates of the features, the position data given by the DGPS is directly compatible with the Jersey mapping. Be able to accomplish the work accurately, quickly, in any weather, and by one person with minimal training.
The Zeno 20 is now compatible with the Collector for ArcGIS App, allowing the data collected/edited to be available in ArcGIS Online almost immediately (an ArcGIS Online subscription is required to use the Collector App).
We are pleased to offer this service at the special pricing of;
Daily hire @ £184.50.
Weekly hire @ £604.75
All prices inclusive of GST.
Systems may be hired on a longer-term basis or permanently. They are also available for lease and purchase if this is of interest.
We are keen to discuss special rates with anyone who is interested in committing to a minimum usage each year, even though you may only require it a day or week at a time.
