General Description

The GPSRXNV-01, produced by R.V.R. Elettronica SpA, is a GPS receiver (Global Positioning System – alias the satellite navigation system developed and maintained by the U.S. Department of Defense), with characteristics that can be used in synchronization systems for isofrequency broadcasting systems (SFN – alias Single Frequency network). The GPSRXNV-01 is designed to being contained into a 19” rack box of 1HE. Two major features of GPSRXNV-01 is compact design and user-friendliness. Another key feature is its modular- concept design: the different functions are performed by modules with most connections achieved through male and female connectors or through flat cables terminated by connectors. This design facilitates maintenance and module replacement. The GPSRXNV-01 contains a buffer battery, to avoid possible lack of power supply, and its internal battery charger. Four LEDs on the front panel provide the following status indications: AC-ON, DC-ON, EBO-OK and GPS- LOCK. The rear panel features the VDE mains input connector with voltage selector that allows to use it with different supply voltages, as well as the ON/OFF switch of the buffer battery, the N-type connector for GPS antenna input, the BNC connector for 1PPS output signal, the BNC connector for 10MHz sync signal and the DB9 connector for status alarm signaling.

Quick guide for installation and use

This section provides a step-by-step description of equipment installation and configuration procedure. Follow these procedures closely upon first power-on and each time any change is made to general configuration, such as when a new transmission station is added or the equipment is replaced. Once the desired configuration has been set up, no more settings are required for normal operation; at each power-up (even after an accidental shutdown), the equipment defaults to the parameters set during the initial configuration procedure. The topics covered in this section are discussed at greater length in the next sections, with detailed descriptions of all hardware and firmware features and capabilities. Please see the relevant sections for additional details.

Preparation

Preliminary checks

Unpack the GPS receiver and immediately inspect it for transport damage. Ensure that all connectors are in perfect condition. Provide for the following (applicable to operating tests and putting into service):

• Single-phase 230 or 115 (-15% / +10%) Vac mains power supply, with adequate earth connection.
• Connection cable kit including:
• Mains power cable.
• Cable to connect the 1 PPS TTL signal (sold separately).
• Cable to connect the 10 MHz signal (sold separately).
• GPS receiver antenna (sold separately).

Preparation of the mains supply

WARNING: perform all the operations described in this section with the main supply disconnected.

The general fuse is accessible from the outside on the rear panel (see figure 6.2). To check the integrity, or for substitution, remove the fuse holder with a screwdriver. The fuse to be used is of type:

Mains Fuse: 1 A 5×20

Note: the switch (with lock position), for the connection of buffer battery, is kept open (BATTERY OFF position) during transport. ). Check this condition and set the switch to ON BATTERY position (see figure 6.2 – note [11]), after powering the system.

Connections

Connect tge GPS ANTENNA input of GPSRXNV-01 (see figure 6.2 – note [11]) to antenna receiver (figure 5.1).

Connect the 10MHz OUT – 1 output of GPSRXNV-01 (figure 6.1 – note [4]) to the proper IN 10MHZ input equipped with apparatus of R.V.R. Elettronica like PTXLCD with SFN option (figure 5.1). If the equipment is of a different brand, identify an equivalent input. Connect the 1PPS OUT TTL – 1 output of GPSRXNV-01 (figure 6.1 – note [8]) to the proper REMOTE input equipped with apparatus of R.V.R. Elettronica like PTX-LCD with SFN option (figure 5.1). If the equipment is of a different brand, identify an equivalent input.

Note: in the following figure is shown the diagram of cable when connecting equipment of R.V.R. Elettronica like the PTX-LCD with SFN option (Figure 5.2).

Connect the power cable in the proper MAINS connector placed on the rear panel (figure 6.2 – note [1]).

Note: The mains must be equipped with adequate ground connection properly connected to the machine. This is a pre-requisite for ensuring operator safety and correct operation.

After connecting the power supply , the receiver performs a bootstrap test lighting on, in sequence, before GPS-LOCK led and then EBO-OK led, soon after light them off. Once that 4 satellites are correctly receipt and decodified, the GPS-LOCK led light on again; when the phase locking of 10MHz e 1PPS signal happens, the EBO-OK will be again light on too. In case that you made an explicit request for purchase the software license of EPSILON BOARD OEM II card at time of order, the reading parameters of GPSRXNV-01 and of satellites will be made through the serial connection between the RS232 and the DB9 placed in front panel and a compatible PC with Microsoft Windows 98, 2000, XP on which you have installed the software furnished. The ALARMS DB9 connector (figure 6.2 – note [3]), from which the signals related to the GPS-LOCK and EBO-OK front LEDs come issued, can be used in SFN systems that require a power lowering in case of failure in GPS synchronism. In case /DST10 option is present (it gives further 3 auxiliary 10MHz outputs and 2 auxiliary 1pps outputs beyond those already available) connect the remaining outputs depending on your system configuration. A connection example is shown here below:
