GNSS.India Asia Seminar

EBGI , Bangalore

Basic Positioning, Navigation,Time : Today

• Navigation satellites are Earth Satellites. Require 24 satellites in MEO (19-24,000 Km altitude) for Global Coverage

• Follow Kepler’s laws of motion, transmit their Position, Navigation, Time (PNT). Range from 4 visible satellites required for (x,y,z,t)

• Provide PNT service through hand-held receivers to users. • Satellites’ orbits and health monitored through an elaborate ground

segment. • C/A Code on L1,No Selective Availability.

• Original Equipment Manufacturers: ACCORD (Jayanto),

SEPTENTRIO (Peter)

Use of GNSS in

• Indian Railways, Defense : ASL (Ramakrishna Rao)

• Industrial applications: EI labs (Vaidyanathan)

• GIS, Land, surveys, photogrammetric mapping: SECON (Appachu)

These industries mostly use GPS L1 receivers. No Indian industry is into

GNSS in mobile phones. Intelligent Transport System yet to use GNSS.

Many Indian industries are unaware of the existence of GAGAN!!

National Council for Applied Economic Review study

National Council of Applied Economic Research (NCAER), Delhi in its report

on “Economic Impact study of Delhi International Airport” dated April 2012 has

reported:

Quote

Contribution to Indian and Regional GDP

Delhi airport’s operations contributed in (2009–10) Rs 294.7 billion (0.45 per

cent) to the national GDP and its contribution relative to Delhi’s GSDP is 13.53

per cent. The total comprises of:

Rs 42.9 billion directly contributed through value added (air transport and

airport services)

Rs 77.2 billion indirectly contributed through supply chain (multipliers

impact).

Rs 174.6 billion in induced impact through tourism and investment.

By 2020, the overall economic impact of Delhi Airport is expected to be approx

Rs 909.5 billion, which will be 0.7 per cent of the National GDP and relative to

Delhi’s GSDP would be 22.2 per cent.

Spectrum for GNSS GNSS spectral bands are:

• L1 (1559 – 1610 MHz),

• L2 (1215 – 1300 MHz),

• L5 (1164 – 1215 MHz),

• S-band (2483.5 – 2500 MHz)

L1 and L2 bands are being used for 30 years now.

L5 is the latest and much sought after band.

S-band is for Regional use in Region 3. The World Radio Conference (WRC-12) discussed global allocation for this band. Proximity of this band with MSS and the 2500-2690 MHz is an added advantage

Spectral bands for Radio Navigation Satellite Systems

All Global Systems have more than 24 satellites each in 19000 – 24000 km altitude

orbits. All transmissions from the satellite to date are in L-band.

The satellites transmit the ephemeris, clock and ionospheric data. The details of the

signal structure and data structure vary slightly.

User receivers measure their distance from atleast 4 satellites through one-way

ranging technique. Most downlink signals use Code Division Multiple Access

(CDMA) and RF modulation such as, BPSK, Binary Offset Carrier (BOC) etc.

GLONASS uses CDMA ranging codes with Frequency Division Multiple Access

(FDMA)

These constellations represent a wonderful laboratory for fundamental scientific work

What’s in store for the future – More satellites, SBASs,

increased QoS, cheaper multifunction chipsets

• 31 GPS, 24 GLONASS,4 GALILEO satellites

• 12 GEOs for SBASs over US, Europe, India and Japan (Korea, Africa,

Canada, South America, South East Asia ?)

• More satellites in view for better ranging solution, accuracies

• More frequencies to eliminate atmospheric errors

• Compatible and Interoperable signal structure

• Positioning and communications integration

• Healthy growth in the GNSS receivers sales internationally

• Increased awareness about GNSS applications in CA and non CA

applications

• GNSS receivers with 76 channels available in Indian market

• GNSS receivers for indoor applications, 32 dB extension in performance

• Synergy between European EGNOS and Indian GAGAN for applications

GPS Space Based Augmentation Systems (SBASs)

• GPS alone is not accurate enough for position accuracies required

for aircraft landing. SBAS improves the accuracy, integrity,

availability and continuity.

• GPS and GEO satellite position is calculated with a large ground

segment of Range and Integrity Monitoring Systems(RIMS)

connected to an Uplink E/S communicating with the augmenting

GEOs.

• GEO transmits improved position, clock, ionosphere and ephemeris

in L1 and L5 centre freq. Info rate is 500 bits/sec.

GAGAN has 15 RIMS and two GEOs at present . Three GEOs are

planned.

• Augmentation is possible through Ground Based Augmentation

System(GBAS) or RAIM.

Benefits of SBASs

• Uniform & Accurate levels of Navigation performance over the entire Airspace and enhanced safety, integrity, continuity and availability for civil aviation.

• Provides coverage of oceanic areas which is not possible by terrestrial systems.

• Improves efficiency and flexibility by increasing use of operator preferred trajectories at all altitudes.

• Improves airport and airspace access in all weather conditions.

• Enhances reliability and reduces delays.

• Reduces workload and improves productivity of air traffic controllers.

• Saves aviation fuel through optimised routes.

• GAGAN can be used on ground for safety critical applications.

EC-India co-operation – Road ahead

• India represents a large and open market

• To serve Indian market Indian presence and tie-ups

are necessary. Many European MNCs have done it:

• Rolls-Royce India, Robert Bosch India, MICO are

leading examples.

• Solve the IPR issues

• Identify Indian partners and suitable applications in

any of the infrastructure development projects

• You may have to deal with Indian Govt. but business

opportunities outside the purview of Govt. are plenty.

• India is a good country to do business with!!

Thank-you for your attention!
