PiLDo Labs: Experience and Role

Wide experience in the GNSS aviation domain:

Technical support to Certification of new GNSS service provision in the aviation domain: EGNOS, GBAS, in the future Galileo and multi-constellation

Support the introduction of GNSS services in aviation:

Aircraft (GIANT, GIANT-2, GBAS trials)

Rotorcraft (HEDGE)

Promotion of GNSS European systems in the Latin America region

ATM Solutions and applications: RNAV procedure design and support tools

Role in METIS Wide Area Demonstrations (Aviation):

Equip Technosky’s aircraft with a GNSS navigation platform

LPV Procedure Design for Çanakkale airport

Support Telespazio for the demonstrations plan definition

Perform database coordination

Support ANSP’s for the installation of ground static receivers

4


Design of LPV in Çanakkale (I)

Process divided in several phases:

EGNOS performances in the region (use of MEDACON Data)

Revision of Çanakkale AIP data information

Coordinated design with DHMI team

Chart generation

Çanakkale Airport

Çanakkale Airport is located in the edge of current EGNOS coverage

AD Coordinates:

40º 08’ 10” N

026º 25’ 29” E

Design of LPV in Çanakkale (IV)

Inputs

DHMI AIP data

ICAO documentation: Doc-8168 (PANS-OPS), Annex 14, Annex 4

Procedure Design Software

AutoLisp Designer Tool (ADT) developed by Pildo Labs

—Annex 14 Surfaces

—Obstacles Identification

Design of LPV in Çanakkale (VI)

CURRENT PUBLISHED NPA (VOR) PROCEDURE

PROPOSED LPV APPROACH PROCEDURECompared to current NPA published procedures in

Çanakkale, LPV offers:

Vertical guidance allowing continuous descent profile

—Benefits in terms of engine noise and pollution

Reduction in the operational minima of more than 900 ft (~270 metres)

Independence from ground navaids

11


Database coding process

LPV procedure is defined by a Final Approach Segment Data Block (FAS DB) with a Channel Number identifier:

The FAS DB is a set of parameters to identify a single LPV during the coding and define its associated approach path (including a CRC reminder)

The Channel Number consists on 5 numeric characters in the range 40000 to 99999 to identify an individual approach during operation

This data is provided to database coders (Jeppesen) to insert it in their systems

Receiver manufacturers (Garmin)

build the receiver’s database

GNSS receivers and platform operation (I)

Garmin GNS480: certified avionics receiver computing deviations for pilots

Septentrio PolaRx2: lab receiver for system monitoring

GNSS receivers and platform operation (II)

Deviations computed by the GNS480 – horizontal only

Results and Lessons Learnt from the trials at Çanakkale (I)

Heritages from previous EU projects (Valencia, San Sebastian, Nice, Sion, Clermont-Ferrand...) re-used and adapted for this location

1st day: 5th November 2009

Intermittent LPV (APV 1) service in the area (edge of EGNOS coverage)

All attempts ending with an ‘Abort Approach’ message in the receiver’s display

2nd day: 6th November 2009

Nice performance of EGNOS SIS

5 approaches flown successfully

Results and Lessons Learnt from the trials at Çanakkale (II)

1st day: 5th November 2009

Intermittent LPV (APV 1) service in the area

All attempts ending with an ‘Abort Approach’ message in the receiver’s display

Example: 1st Approach

HPL > HAL = 40m

LATITUDE

LONGITUDE

Approaches aborted, not downgraded, due to the lack of LNAV minima in the chart

17


Results and Lessons Learnt from the trials at Peruggia (I)

Heritages from previous EU projects (Valencia, San Sebastian, Nice, Sion, Clermont-Ferrand...) re-used and adapted for this location

11th November 2009

Nice performance of EGNOS SIS
