Positioning subject presentation

POSITIONING

• Positioning:– Determination of mobile or stationary objects in space.– Location of an object in a specified coordinate system.

POSITIONINGINTRODUCTION

• Positioning mechanisms:

POSITIONINGINTRODUCTION

• Positioning mechanisms:– GNSS– Mobile phone tracking

• Multilateration of radio signals between cell towers and the phone.– WLAN (Wireless Local Area Network)

• Locating mobile network devices.– UWB Ultra Wide Band

• Radio technology that can use a very low energy level for short‐range,high‐bandwidth communications over a large portion of the radiospectrum.

– WIFI• Measuring the intensity of the received signal.• WPS (Wi‐fi Positioning System).  Software contining Wi‐fi positions.

– Submarine quantum positioning• Accelerometers based on super‐cooled atoms could keep track of position with stunning precision.

POSITIONINGINTRODUCTION

• Techniques:– Many.– Here we’ll use GNSS technologies.

POSITIONINGINTRODUCTION

• GNSS in ordinary life:– Smartphones.– Watches.– Tablets.– Vehicle navigators.– Precision agriculture.– Mining.– Surveying and Geodesy.– …

POSITIONINGGNSS TECHNIQUES

• GNSS and positioning.

POSITIONINGGNSS TECHNIQUES

• In this subject:– Calculation algorithms.– Scientific software (Bernese).– Differential GNSS.– Precise Point Positioning (PPP).– Kinematic GNSS.

POSITIONINGGNSS

• We need to study:– Reference systems.– Reference frames.– Permanent GNSS networks.

POSITIONINGGNSS

• Applications:– Weather.– Transport.– Precision agriculture.– Deformations.

POSITIONINGGNSS

• Satellite navigation and earth observation areprobably the space sector with the greatestgrowth potential both in terms of systemsdevelopment (upstream) and businessopportunities in application development(downstream).– (Javier Ventura. Valencia 2013)– Spokesman for theEuropean Space Agency in Spain

POSITIONINGMARKET

• Geolocation and positioning services required by:– Transport.– Communications.– Precision agriculture.– Emergency services.– Shiping…

• GNSS market prospects:– More than 95% of the market is focused on location‐based services (LBS, integrated mobile) andautomobile transport services.

– Other important sectors are agriculture, marine, railtransport, aviation, energy and scientific applications.
