Standpoint™
Live sky synchronization solution
for Spirent GNSS simulators

Key benefits
Realism

GNSS simulators are used in labs around the world to develop and test robust
positioning, navigation and timing systems. Unlike live sky testing, simulators
provide full control of the satellite signals and environmental conditions ofthe test. Simulations can include scenarios for any location, from Earth to theMoon, and at any time past, present or future.
For some applications, the ability to synchronize the simulation time and/or orbital parameters with the live sky GNSS time and ephemeris is critical.
Spirent Standpoint addresses this need, enabling simple and precise
synchronization in the lab or in the field.

Introducing Standpoint
Standpoint comprises two key components: the Standpoint Reference
Receiver and the Standpoint Software Utility.
Standpoint Reference Receiver
The reference receiver acquires the live sky GNSS signals from an active
antenna (provided), synchronizes the Spirent GNSS simulator via 1PPS and
10 MHz signals, and passes live sky satellite data to the simulator via a USBconnection.
Standpoint Software Utility
The Standpoint Software Utility is a web service application used to control
the reference receiver and communicate with the simulator control software– PosApp. The utility is installed on the simulator’s controller, or on a separatecontroller, if required.

Use case:
Lab-based live sky
synchronizationThe first task when connecting any device under test(DUT) to a GNSS simulator is to cold start the GNSSreceiver. This clears position, time, almanac andephemeris from the module’s memory. However, insome cases, cold starting the receiver is not possible:• When the receiver is embedded in a product withno access to cold start• When the DUT uses another live time source thatmust match the receiver time (e.g. in-vehicle
infotainment getting time from GNSS and cellular)• When long time to first fix (TTFF) impacts timeconstraints
Standpoint overcomes the need to cold start the GNSS
receiver by aligning the time, almanac and ephemerisof the GNSS simulator with real world signals.

Standpoint

Use case:Spoofing testing
Spoofing testing can be conducted by coupling two
synthetic signals generated by a GNSS simulator. With
direct control over both the “real” and spoofed signals,
it is relatively simple to align pseudoranges. However,this method is very much a worst-case scenario. Using
live sky signals represents a better test case - spoofing
a device that is positioning using real signals moreaccurately represents real-world operational threats.
However, the first epoch of simulation must be tightlyaligned to the real signals, and this makes the test
set-up more complicated. Standpoint is capable ofsynchronizing to live sky with an accuracy of 50 ns.
This enables realistic spoofing testing, with live sky
signals providing the truth data, and complete user
control over the spoofed signals. Standpoint integrates
seamlessly with Spirent GSS7000 and GSS9000 GNSS
simulators, making set-up of spoofing tests easier andfaster than ever before.
