1. GNSS and GNSS Market
• A GNSS (Global Navigation Satellite System) is a satellite-
based system that allows a user to determine its position and
velocity anywhere at any time, and to synchronize its clock
with the ultra precise GPS time.
• The most well-known GNSS is GPS (Global Positioning service)
which use has significantly increased in the recent years
• The number of applications and services
dependent upon positioning, navigation,
and timing has been drastically increasing
since GPS has been available to civil
users.

1. GNSS and GNSS Market
Basic principles of GNSS (1/2):
• Each GNSS satellite broadcasts a signal towards the Earth. This signal
contains a time-tagged navigation message including:
– the ephemeris of the transmitting satellite (a prediction of the satellite position),
– The estimated drift of the satellite internal clock compared to GPS time
• The receiver then
– compares the time of broadcast of the received signal with the time of
reception (measured by an internal clock) this corresponds to the propagation
time (that includes true propagation time + receiver/satellite clock drift + propagation
errors + reception errors). This can be transformed in a pseudo-range
measurement by multiplying the measured propagation time by the speed of light.
– read the transmitted navigation message to determine the satellite position and
clock drift with respect to GPS time
• With at least 4 such measurements, the receiver can then solve for its 3-D
position and its internal clock drift compared to GPS time using multi-
lateration.

1. GNSS and GNSS Market
Basic principles of GNSS (2/2)
• As a consequence, a GNSS is split into 3 segments:
– The space segment:
• with a constellation of 24 to 30 MEO satellites (~20,000 km altitude) in order for
the receiver to always have at least 4 satellites visible
• GNSS satellites need stable atomic clocks on-board to limit the satellite clock drift
– The ground segment that is composed of a network of stations that:
• Monitor the transmitted GNSS signals characteristics
• Compute continuously predictions of the satellites’ position as well as
satellites’ clock drift with respect to GPS time
• Upload these predictions to the satellites so that it is transmitted to the user.
– The user segment:
• Has to acquire and track the signals coming from the satellites in view
• Has to read the transmitted message
• Has to compute the pseudo-ranges and the user position

1. GNSS and GNSS Market
• GNSS device shipments will grow on average 10% per year
over the next decade reaching 1.1 billion shipments by 2020.
• The global market for GNSS products and services to grow to
€250 billion by 2030. Foreseen annual growth rate of 11%
• Mass market: – The penetration of GNSS in mobile phones is expected to increase very quickly,
from some 20% today to above 50% within the next five years. Forecast of 1
billion cell phones per year sold in 2020
• Road market: – The penetration of receivers in road vehicles, today at 30%, will exceed 80% over
the next decade.
• Aviation: – 140,000 receivers sold per year in 2020.
• Agriculture: – More than 500,000 receivers sold per year in 2020 (growth of 16% per year)
• Vendors are using innovation as a differentiator

2. MSc Objectives and Framework
• The European Commission project “ERIG” (Education,
Research and Innovation in GNSS) put into light that “there is a
lack of education in GNSS fundamental techniques” to
provide operational young graduated staff to the growing job
market of GNSS and GNSS-dependent companies
• ERIG also defined the idea of Centres of Excellence (CoE) in
GNSS: a location where education, research and innovation is
performed of world standard, in terms of measurable scientific
production (including training) and technological innovation
– 3 main European CoEs in GNSS were recognized:
• Toulouse (France),
• Munich (Germany), and
• Torino (Italy).
- 10 -
2. MSc Objectives and Framework
• In response to the growing demand for qualified experts, and
based on the recommendation from the ERIG project, the
Ecole Nationale de l’Aviation Civile (ENAC) and the Institut
Supérieur de l'Aéronautique et de l'Espace (ISAE) in
Toulouse, France, have developed a new Master of Science
(MSc) in GNSS that has started in Sept. 2012.
• It is a 2-year programme that aims at providing an advanced
training in satellite-based positioning as well as
telecommunications.
• All classes are taught in English.
- 11 -
2. MSc Objectives and Framework
• A European Framework: – The development of the MSc was supported financially by the European
Commission and the European GNSS Agency (GSA)
– The 3 European GNSS CoE are partners through the participation
(teaching and internship) of their most recognized research laboratories :
• Politecnico di Torino (Italy), and
• Universität der Bunswehr Munich (Germany)
• The MSc is recognized by the French Ministry of Higher
Education it is compliant with the Bologna process.
• The MSc will take place in the premises of ENAC, Toulouse,
France.
