EuroPak-15a Receiver User Manual Rev 5

Chapter 1

Introduction

This chapter provides information on the features and functionality of the EuroPak-15a and how it operates in 
the context of an SBAS system.

1.1

Overview of the EuroPak-15a

The EuroPak-15a is a high-performance GPS, Galileo and GEO receiver capable of receiving and tracking 
sixteen GPS L1, GPS L5, Galileo L1 and Galileo E5a signals. Alternatively, four of the sixteen signals can be 
SBAS GEO L1 and SBAS GEO L5 signals. The EuroPak-15a also decodes the navigation signals.

There is flexibility in areas such as configuration and specification of output data and control signals. Multiple 
software models are available, allowing you to better fit the receiver to the application while maintaining the 
option for a compatible upgrade path.

The EuroPak-15a enclosure offers a complete solution, a protective enclosure that provides an interface to the 
receiver card’s power, data, and status signals.

1.2

SBAS Overview

A Satellite-Based Augmentation System (SBAS) is a safety-critical system designed to augment the 
Department of Defense Global Positioning System (GPS) Standard Positioning Service (SPS). SBAS enhances 
GPS service by providing:

•

a ranging function to the SBAS satellites, which improves signal availability and reliability 

•

GPS signal corrections, which improve accuracy

•

integrity monitoring, which improves safety

The primary mission of the SBAS system is to provide a means for air navigation for all phases of flight in the 
National Airspace System (NAS) from departure, through en route, and approach. The principal functions of 
SBAS include:

•

determining ionospheric corrections

•

determining satellite orbits

•

determining satellite clock corrections

•

determining satellite integrity

•

independent data verification

•

SBAS message broadcast and ranging

•

system operations & maintenance

As shown in 

Figure 1

 on 

Page 17

, the SBAS system consists of a series of 

Reference Stations

 and 

Master 

Stations

, a 

Ground Uplink Subsystem

, and 

Geostationary Satellites

 (

GEOs

). The 

Reference Stations

, which are 

strategically located to provide adequate coverage, pick up GPS satellite data and route it to the 

Master 

Stations

. The 

Master Stations

 then process the data to determine the signal integrity, signal corrections, and 

residual errors for each monitored satellite. This information is sent to the 

Ground Uplink Subsystem

 for 

transmission to the 

GEOs

, which then re-transmits the data on the GPS L1 and L5 (not yet available) 

frequency. In the future, the system will support L5 signal frequency broadcasts.
