New network of permanent GNSS Reference Station 

"PEGASO NOW" is a national network of permanent GNSS reference station, certified by the Italian Military Geographic Institute – IGM.  It provides immediate access to real-time GNSS adjustments (RTK) for precision positioning over the Italian territory: adjustments are provided according to the types used by the international scientific community. The new network deploys more than 190 latest-generation permanent GNSS reference station positioned throughout Italy.

Pegaso VRS Now is the new network of Virtual Reference Station (VRS) resulting from the public-private partnership between: Istituto Geografico Militare (Italian Military Geographic Institute), Difesa Servizi and Trimble.

• RTK Level Accuracy
  Centimeter accuracy, helps you always be sure of your position.
• Quick initialization
  With immediate access to RTK network adjustments, you can start working very quickly, even without base station configuration.
• The system uses the latest constellations
  (GPS Gen III, GLONASS, Galileo, QZSS e BeiDou-III)
  You can work more reliably even in harsh environments, reducing re-processing and increasing productivity on site.
• Easy to use, it improves work efficiency
  Just connect, receive adjustments, and measure. Through all receivers used as rovers, you can deploy multiple teams and work simultaneously.
• Customer support
  24/7 network monitoring and maintenance with 24-hour customer support.
• Affordable
  A reasonably priced annual subscription provides year-round access to reliable, high-precision intra-network adjustments.
• Redundant benefits.
  As there are many reference station there is no need to use one of your own.

• Reference Systems

For using the Pegaso VRS network, you must have an annual subscription, a reliable mobile connection (GSM, GPRS or UMTS, if available) and a dual-frequency GPS receiver compatible with industry-standard RTCM adjustments.

Fixed reference station in the Pegasus VRS network receive data from GNSS satellites and send them to the VRS server. Each GNSS rover connects to the Pegasus server and communicates its position. A "virtual" reference station is thus generated for that specific receiver.  The VRS server calculates and applies customized adjustments, reducing atmospheric interferences from satellite data. After some checks about data integrity, the "virtual" reference station sends a verified set of adjustment data to the receiver via mobile modem.

This service is implemented and sold by Trimble. Please visit the following link to choose between different kind of subscriptions and purchase details.

1. What is VRS Pegasus Network?
   The VRS Pegasus is a network of GNSS permanent reference station operated by Trimble, a leading surveying and geospatial technology company, in collaboration with the IGM (Italian Military Geographic Institute). This service provides high-precision NRTK adjustment services able to achieve accurate and reliable 24/7 GNSS positioning.
2. What are the characteristics of this network?
   This is the only network in Italy certified and calculated directly by the Italian Military Geographic Institute. It was created and designed ex novo to provide the highest quality and efficiency in terms of geographic coverage by using latest generation instruments (Alloy receivers).
3. Where is it possible to work with Pegaso VRS Network?
   Pegaso VRS offers total coverage in all regions of Italy (including coasts, major and minor islands), enabling access to high-precision adjustment data. All stations making up the network are strategically deployed to provide reliable service throughout the country.
4. How to purchase and how much do subscriptions cost?
   To purchase a subscription, please visit the following link where you can find different kinds of subscriptions and purchase details.
5. Is it possible to use VRS Pegasus Network with any GNSS device?
   Network VRS Pegasus is compatible with all GNSS sensors able to use this service. It only needs to be checked if the device supports the "NTRIP" protocol (Networked Transport of RTCM via Internet Protocol), which is essential for connecting - via Internet - to the GNSS reference station network.
6. Is it also possible to use RINEX data?
   By accessing the specific portal, it is possible to download RINEX data in any desired format, either from single CORS or in VRS format, with samples ranging from 1 to 30 seconds.
7. In what reference system is Pegasus framed?
   Real-time adjustments and RINEX data allow to get accurate positions in the Official National Geodetic Reference System managed by the IGM: ETRF2000 implementation, epoch 2008.0, of the European ETRS89 system.
