EuroPak-15a Receiver User Manual Rev 5 23
Chapter 2 Installation
This chapter contains instructions and tips to set up your NovAtel receiver to create a GNSS receiver system.
At the time of publication, it is recommended that the L5 signal for the receiver be generated by a signal
generator as there are no L5 signals in space.
2.1 Additional Equipment Required
In order for the receiver to perform optimally, the following additional equipment is required:
• An interface for power, communications, and other signals
• An antenna or signal generator
• A quality coaxial cable (and interconnect adapter cable as necessary)
• Data communications equipment capable of serial communications
• A serial cable (if not included with the receiver)
• A power supply
• A power cable (if not included with the receiver)
CAUTION:When the EuroPak-15a receiver is installed in a permanent location, such as in a
building, it should be protected by a lightening protection device according to local
building codes. See also Warranty Policy on Page 13.
2.1.1 Selecting an Antenna or Signal Generator
An L5 Signal Generator is available from NovAtel, see the Aviation Group’s contact information on Page 14 to
learn more.
The GPS-704-X antenna is a wide band passive antenna available from NovAtel. It is designed to operate in the
frequency range 1150-1650 MHz. An external LNA is required.
NovAtel offers a variety of antenna models. Each offer exceptional phase-center stability, a significant measure
of immunity against multipath interference and has an environmentally-sealed radome.
Connection at the time of publication is directly to a signal generator. There are no L5 signals in space at
the present time.
2.1.2 Choosing a Coaxial Cable
An appropriate coaxial cable is one that is matched to the impedance of the antenna or signal generator and
receiver being used (50 ohms), and whose line loss does not exceed 10.0 dB. If the limit is exceeded, excessive
signal degradation will occur and the receiver may not be able to meet its performance specifications. NovAtel
offers a variety of coaxial cables to meet your interconnection requirements, including:
• 5, 15, or 30 m RF cables with TNC male connectors on both ends (NovAtel part numbers C006, C016
and C032 respectively)
Your local NovAtel dealer can advise you about your specific configuration. Should your application require
the use of cable longer than 30 m you will find the application note RF Equipment Selection and Installation at
our website, www.novatel.com
, or you may obtain it from NovAtel Customer Service directly.
High-quality coaxial cables should be used because a mismatch in impedance, possible with lower quality
cable, produces reflections in the cable that increase signal loss. Though it is possible to use other high-quality
RF cables, the performance specifications of the EuroPak-15a receivers are warranted only when used with
