2 Safety instructions for building-in equipment
This building-in equipment has been designed and tested in accordance with the requirements of Standard
IEC60950-1 "Safety of Information Technology Equipment, including Electrical Business Equipment".
During installation of the building-in equipment in an end application (i.e. rack) additional requirements in
accordance with Standard IEC60950-1 have to be taken into account.
• The building-in equipment is a class 1 - equipment and must be connected to an earthed outlet
(TN Power System).
• The building-in equipment has been evaluated for use in oce environment (pollution degree 2) and may be
only used in this environment. For use in rooms with a higher pollution degree more stringent requirements
are applicable.
• The building-in equipment may not be opened.
• Protection against re must be assured in the end application.
• The ventilation opening may not be covered.
• The equipment/building-in equipment was evaluated for use in a maximum ambient temperature of 40
◦
C.
• For safe operation the building-in equipment must be protected by max 16 A fuse in the power installation
system.
• Disconnection of the equipment from mains is done by pulling the mains plug.

3 General Information GPS
The satellite receiver clock GPS170 has been designed to provide extremly precise time to its user. The clock has
been developed for applications where conventional radio controlled clocks cant meet the growing requirements
in precision. High precision available 24 hours a day around the whole world is the main feature of this system
which receives its information from the satellites of the Global Positioning System.
The Global Positioning System (GPS) is a satellite-based radio-positioning, navigation, and time-transfer sys-
tem. It was installed by the United States Departement of Defense and provides two levels of accuracy: The
Standard Positioning Service (SPS) and the Precise Positioning Service (PPS). While PPS is encrypted and only
available for authorized (military) users, SPS has been made available to the general public.
GPS is based on accurately measuring the propagation time of signals transmitted from satellites to the users
receiver. A nominal constellation of 24 satellites together with several active spares in six orbital planes 20000
km over ground provides a minimum of four satellites to be in view 24 hours a day at every point of the globe.
Four satellites need to be received simultaneously if both receiver position (x, y, z) and receiver clock oset from
GPS system time must be computed. All the satellites are monitored by control stations which determine the
exact orbit parameters as well as the clock oset of the satellites on-board atomic clocks. These parameters
are uploaded to the satellites and become part of a navigation message which is retransmitted by the satellites in
order to pass that information to the users receiver.
The high precision orbit parameters of a satellite are called ephemeris parameters whereas a reduced precision
subset of the ephemeris parameters is called a satellites almanac. While ephemeris parameters must be evaluated
to compute the receivers position and clock oset, almanac parameters are used to check which satellites are in
view from a given receiver position at a given time. Each satellite transmits its own set of ephemeris parameters
and almanac parameters of all existing satellites.

4 The Modular System GPS170BGT
GPS170BGT is a set of equipment composed of a satellite controlled clock GPS170 together with a power supply
unit (see chapter power supply), both installed in a metal 19" Modular chassis and ready to operate. The inter-
faces provided by GPS170 are accessible via connectors in the rear panel of the case. Details of the components
are described below.
