the appropriate data file defined in Annex A or Annex B.
Where the assistance data is fixed or is not required on a per-satellite basis, then it is defined in the following
subclauses. Where assistance data is required on a per-satellite basis, or where the values of the data also vary with time
then it is specified in comma-separated-variable files in the appropriate data file defined in Annex A or Annex B. These
files specify the values to be used for each satellite, indexed by satellite PRN or SV ID, and, where applicable, the
values to be used indexed by both time and satellite PRN or SV ID.
All the Assistance Data information elements are given with reference to TS 44.031 [5], where the details are defined.

signalling tests
5.1.1 General
This subclause defines the GPS scenario and the associated assistance data that shall be used for all Assisted GPS
signalling tests defined in TS 51.010-1 [4] subclauses 70.7 to 70.9.
The satellite simulator (SS) shall generate the six satellite signals defined in subclause 5.1.2 and shall provide assistance
data as defined in subclauses 5.1.3 to 5.1.8.
Where assistance data is required on a per-satellite basis, or where the values of the data also varies with time it is
specified in comma-separated-variable files in the GPS_data.zip file defined in Annex A. These files specify the values
to be used for each satellite, indexed by satellite PRN, and, where applicable, the values to be used indexed by both time
and satellite PRN.
Assistance data that is marked as "time varying" and the GPS TOW field are only specified and used in 0.96 second
increments. Interpolation between these values shall not be used.
The accuracy of the GPS TOW and assistance data that is marked as "time varying" in the provided assistance data shall
be within +/- 2 s relative to the GPS time in the system simulator.
Assistance data Information Elements and fields that are not specified shall not be used.
5.1.2 GPS Scenario

5.2 GPS Scenarios and Assistance Data for Assisted GPS
Minimum Performance tests
5.2.1 General
5.2.1.0 Introduction
This subclause defines the GPS scenarios and assistance data IEs which shall be available for use as specified in all A-
GPS Minimum Performance test cases defined in TS 51.010-1 [4] subclause 70.11.
The information elements are given with reference to TS 44.031 [5], where the details are defined.
Subclauses 5.2.2 and 5.2.3 list the assistance data IEs required for performance testing of MS-based mode, and
subclauses 5.2.4 and 5.2.5 list the assistance data available for performance testing of MS-assisted mode. Subclause
5.2.6 lists the values of the assistance data IE fields for all performance testing.
The A-GPS minimum performance requirements are defined by assuming that all relevant and valid assistance data is
received by the MS in order to perform GPS measurements and/or position calculation. This subclause does not include
nor consider delays occurring in the various signalling interfaces of the network.
5.2.1.1 Satellite constellations and assistance data for performance testing
The satellite constellations for performance testing shall consist of 24 satellites. Almanac assistance data shall be
available for all these 24 satellites. At least 9 of the satellites shall be visible to the MS (that is above 5 degrees
elevation with respect to the MS). Other assistance data shall be available for 9 of these visible satellites. In each test,
signals are generated for only a subset of these satellites for which other assistance data is available. The number of
satellites in this subset is specified in the test. The satellites in this subset shall all be above 15 degrees elevation with
respect to the MS. The HDOP for the test shall be calculated using this subset of satellites. The selection of satellites for
this subset shall be random and consistent with achieving the required HDOP for the test.
5.2.1.2 GPS Scenarios for performance testing
5.2.1.2.0 General
This subclause defines the GPS scenarios that shall be used for all Assisted GPS performance tests defined in subclause
TS 51.010-1 [4] subclause 70.11.
The GPS scenarios achieve the required HDOP for the Test Cases as defined in the Requirements specification TS
45.005 [8]. They also satisfy the requirement that for each test instance the reference location shall change sufficiently

5.2.1.2.4 MS Location for TTFF test cases
5.2.1.2.4.0 General
This subclause defines the method for generating the random MS locations that are required to be used for the TTFF
tests defined in TS 51.010-1 [4] subclause 70.11.
For every Test Instance in each TTFF test case, the MS location shall be randomly selected to be within 3 km of the
Reference Location. The Altitude of the MS shall be randomly selected between 0 m to 500 m above WGS-84 reference
ellipsoid. These values shall have uniform random distributions.
ETSI
3GPP TS 51.010-7 version 9.5.1 Release 9 13 ETSI TS 151 010-7 V9.5.1 (2013-02)
The MS location is calculated as an offset from the Reference Location.
5.2.1.2.4.1 MS Location Offset
The MS location offset shall be calculated by selecting the next pair of random numbers, representing a pair of latitude
and longitude offsets in degrees, from a standard uniform random number generator, with the following properties:
The ranges of the latitude and longitude offsets values shall be such that when translated onto the surface of the
earth they shall lie within a 3km radius circle, centred on the Reference location specified for the GPS scenario
under consideration. For the purposes of this calculation make the following assumptions:
a) Over the 3km radius circle at the Reference location the earth is flat and the meridians and parallels form
a rectangular grid
b) The earth is spherical with a radius of 6371141m (equal to the WGS 84 value at 35 degrees latitude)
The resolution used for the latitude and longitude offsets values shall be 90/2E23 for the latitude offset values
and 360/2E24 for the longitude offset values, representing the coding resolution in degrees specified in 3GPP TS
23.032 [7].
5.2.1.2.4.2 MS Altitude
The MS altitude value shall be calculated by selecting the next random number from a standard uniform random
number generator, in the range 0 to 500, representing meters. The resolution used for the random number shall be 1,
representing 1 meter.
5.2.1.2.5 Satellites to be simulated in each test case
The satellites to be simulated in each test case have been selected in order to achieve the required HDOP for that test
case.
