It is important that you complete the owner information and return the card to us to receive full warranty benefits. Safety notices WARNING: Navigation aid Although we have designed this product to be accurate and reliable, many factors can affect its performance. As a result, it should only be used as an aid to navigation and should never replace common sense and navigational judgement. Always maintain a permanent watch so you can respond to situations as they develop. WARNING: Product installation This equipment must be installed and operated in accordance with the instructions contained in this handbook. Failure to do so could result in poor product performance, personal injury and/or damage to your boat. WARNING: Electrical safety Make sure the power supply is switched off before you make any electrical connections. WARNING: Servicing There are no user-serviceable parts in this unit. Do NOT attempt to open the unit or service the equipment. If the unit develops a fault, return it to your nearest distributor for service. EMC conformance All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment. The design and manufacture of Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Chapter 1: About SD-GPS (RS120 only) 1 Chapter 1: About SD-GPS (RS120 only) 1.1 Satellite Differential GPS on the Raystar 120 The Raystar 120 Satellite Differential GPS (SD-GPS) Receiver uses the new satellite differential system to improve the accuracy, integrity and availability of the basic GPS signals. This provides greater positional accuracy compared with standard GPS receivers (e.g. Raystar 112LP). Three separate and compatible SD-GPS systems currently exist or are being developed: 1. Wide Area Augmentation System (WAAS), developed by the Federal Aviation Administration (FAA). 2. European Geostationary Navigation Overlay System (EGNOS), being developed by a European consortium. 3. MTSAT Satellite-Based Augmentation System (MSAS), being developed by the Japan Civil Aviation Bureau (JCAB). 1 About SD-GPS (RS120 only) 1.2 SD-GPS in North America (WAAS) How SD-GPS works The following description is based on WAAS, but the same principles apply to the EGNOS and MSAS networks. As shown in Figure 1-1, the WAAS network consists of: · · · ground reference stations across the USA master stations located at East Coast and West Coast two geostationary satellites located above the equator This network operates in conjunction with the existing GPS satellites. The ground reference stations are located at known positions and receive data continuously from the GPS satellites. The ground reference stations transmit their data to the master stations, which calculate the error of the GPS-received positions and generate correctional data. The master stations send their corrected `differential' signals to the two geostationary satellites which broadcast the corrected data on the standard GPS frequency. 2 Raystar 120 & Raystar 112LP GPS Receivers - Owner's Handbook 1 About SD-GPS (RS120 only) D4903-1 Figure 1-1: The WAAS System Your Raystar 120 SD-GPS Receiver can then use this correctional data to refine the GPS positional data it receives. This results in improved accuracy (typically less than 3 metres) compared with standard GPS (typically 15 m) or land-based DGPS (typically 10 m). Availability of WAAS in North America The area coverage of WAAS includes the entire United States of America (see Figure 1-2). 135°E 75°N 150°E 165°E 180° 165°W 150°W 135°W 120°W 105°W 90°W 75°W 60°W 45°W 30°W 15°W 0° 15°E 60°N 45°N 30°N 15°N 0° 15°S D4910-1 Figure 1-2: WAAS Coverage Map Chapter 1: About SD-GPS (RS120 only) 3 At the time of going to print, WAAS was being tested for aviation use. During this testing and certification period, continuous service is expected although brief signal outages may occur as refinements and upgrades are made to the system. Information about the status of WAAS and any planned outages are available via the Raymarine website at: http://www.raymarine.com 1 About SD-GPS (RS120 only) 1.3 SD-GPS coverage outside North America As well as being WAAS compatible, the Raystar 120 is also compatible with the SD-GPS networks being developed for Europe (EGNOS) and Asia (MSAS). The combination of the WAAS, EGNOS and MSAS systems will provide global satellite based differential GPS augmentation into the future. Europe (EGNOS) At the time of going to print, EGNOS was in early testing and qualification phases. As a result, signal outages may occur at any time. The status of EGNOS and any planned outages are available on-line at the Raymarine website: http://www.raymarine.com Satellite differential is currently disabled outside the WAAS reception area. When EGNOS is qualified for navigational use, we will publish a procedure on the Raymarine website to enable EGNOS operation. Asia (MSAS) An Asian satellite differential system (MSAS) is also being developed. When MSAS is qualified for navigational use, we will publish a procedure on the Raymarine website to enable MSAS operation. 1.4 Accuracy & continuation of broadcast coverage CAUTION: The navigational accuracy of equipment using these satellite broadcast SD signals during the testing and qualification phases is not guaranteed by Raymarine Limited, nor is the continuation of the broadcast SD signals the responsibility of Raymarine Limited. 4 Raystar 120 & Raystar 112LP GPS Receivers - Owner's Handbook 1 About SD-GPS (RS120 only) Chapter 2: Installation 5 Chapter 2: Installation The sections in this chapter explain how to install the Raystar 120/112LP receivers: Section Section 2.1, Planning the installation Section 2.2, Selecting a suitable location Section 2.3, Mounting the receiver Page 5 8 9 CAUTION: Before starting installation ensure you have the correct unit for your application.The Raystar 120/112LP compatibility table on page 18 identifies the correct version of the Raystar 120/112LP Receiver for compatible Raymarine, Autohelm and Apelco units.
