Basic Positioning, Navigation,Time : Today
10-20 m
• 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.

Participating industries in the seminar today
•
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)
• Education through tablet PCs : EPIGON (JK)
• Precision agriculture : Dr.Jaganath Rao ,Bangalore
• GIS, LBS, Fleet management: MAGNASOFT (Bobbie)
• Aviation: Airports Authority of India (Sudhir, GM,AAI)
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!!
ISRO experimenting with GPS occultation for accurate temperature profiles
for weather prediction.

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

GALILEO
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

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!!
