Hence, the aims of the present study were (1) the development of an automated subtechnique identification system using angular rate sensors, and (2) the examination of the relationships among the skiing velocity, course conditions, and subtechniques using a DGNSS and an automated identification system.
The downhill zones can be distinguished using the position or altitude data of the DGNSS. Thus, the accuracy of identification will be improved by not applying this method during the downhill section.
In this study, we used an automatic method to identify the subtechniques, and used a small DGNSS module to measure the velocity and course grade.

The demonstrator simulates a conventional and a reverse DGNSS
system as used with Galileo, comprising, on the one hand, the usual service centre components for recording, calculating and transmitting raw and correction data, and, on the other hand, a rover component for receiving and visualizing this information.
The SAILOR 656X GNSS and SAILOR 657X DGNSS join the already available SAILOR 6391 Navtex and SAILOR 628X AIS as new generation SAILOR products designed to work with the SAILOR 6004 Control Panel.
The SAILOR 656X GNSS and the SAILOR 657X DGNSS collect satellite data from any available navigation satellites including GPS and GLONASS and distribute it to a variety of on board systems such as; ECDIS (Electronic Chart Display System), INS (Integrated Navigation System), GMDSS (Global Maritime Distress & Safety System), SATCOM (Satellite Communication System), MCS (Master Clock Systems) and PABX (Telephone Exchanges).
The SAILOR 6560 GNSS System and SAILOR 6570 DGNSS System are delivered with the SAILOR 6004 Control Panel and the corresponding SAILOR 6285 GNSS Antenna or SAILOR 6286 DGNSS Antenna, while the SAILOR 6561 GNSS Basic and SAILOR 6571 DGNSS Basic are delivered with the antennas only.
All four variants use the same proprietary SAILOR 6588 DGNSS Receiver, which provides highly accurate data, enhanced by means of Satellite Based Augmentation System (SBAS) from various areas including WAAS (Wide Area Augmentation System) for the United States, EGNOS (European Geostationary Navigation Overlay Service) in Europe in addition to systems from Japan, India and Russia.
The new Trimble SPS356 DGNSS
Beacon Receiver is available now through Trimble's Marine Dealer Channel.
Trimble introduced today its new Differential Global Navigation Satellite System (DGNSS) infrastructure software package for marine navigation TrimbleA Beacon.
The unique modular Pivot Platform freely allows DGNSS service providers to set up their beacon landscape in a variety of system configurations from a stand-alone DGNSS beacon station to multiple networked DGNSS beacon stations, which can be centrally operated and managed to minimize the maintenance of remote locations.
