What will new/modernized GNSS bring?
Increased
number
of
observations
Wider frequency band
Dual
frequency
measurements
New codes
Improved data structure
No significant decrease of
DOP
Higher size, cost, power
Higher size, cost, power
Ok

Market characteristics
B2C (Business to consumer)
Low margin, high volume
Commoditized
Cost
competition
Need for
differentiation
Irrational,
non-professional
buyers

Multisystem GNSS for mass
market…
….will come up
….will be (initially) more expensive
….will not provide true differentiation point
…. will not overcome intrinsic limitations of satellite
navigation
No indoor
navigation
Severe
multipath
vulnerability
Low
interference
immunity

Alternatives are out there
WiFi positioning system (WPS)
Gyro + clocks (TIMU)

Multisystem GNSS for mass
market…
….will come up
….will be (initially) more expensive
….will not provide true differentiation point
…. will not overcome intrinsic limitations of satellite
navigation
….will be integrated with non-GNSS sensors
….may degrade to single system after integration

Multisystem GNSS for professional
market…
…. has existed for 20 years
…. will develop further
…. will make use of advanced Multi-GNSS features
RTK and other
carrier-based
methods
Higher accuracy,
availability,
continuity
