|
|
Area of accessibility
|
|
Worldwide
|
|
GATE Test area of approx. 65 km² (core area
about 25 km²) south-east from Munich
|
|
|
|
Attainable HDOP and VDOP values
|
|
Average HDOP between 1.5 and 2.5; Average
VDOP between 2 and 3 '
|
|
In the core area: HDOP: < 2; VDOP 6-20 ;
NB: these values hold for the real physical GTS constellation;
in the 'Virtual Satellite Mode' the DOPs of the actual Galileo
constellation are obtained. VDOP 2-3 in combination with GPS
/ Galileo-IOV / GSTB-V2 satellites.

|
Positioning accuracy
|
|
Open Service' positioning accuracy (95%):
Single frequency: H = 15 m, V= 35 m Dual frequency: H = 4
m, V= 8 m
|
|
Horizontal
(single frequency):
10 m
Horizontal Goal
(two frequencies):
2 - 5 m
Vertical Goal
(stand-alone): 30 m
Vertical Goal (GPS/GSTB-V2/Galileo): 15 m
|
|
|
|
Carrier-frequencies
|
|
3 carrier-frequencies
|
|
All 3 carrier-frequencies with their bandwidths
are emitted in the test area

Codes
|
|
Not yet specified definitely
|
|
The goal is the emission of the GALILEO
codes. Here, GATE has been designed to allow the greatest
possible flexibility.

|
|
Integrity
|
|
Full SIS integrity control
|
|
SIS integrity flag will also be emitted.
Integrity processing, however, is not currently planned for
GATE routine operations
|
|
|
|
Atmospheric conditions
|
|
Ionosphere Troposphere
|
|
Signal propagation delays through the ionosphere
and the troposphere are realistically emulated in GATE ('Virtual
Satellite Mode').
