Cospas/Sarsat analysis:
Reception and analysis/decoding of Cospas/Sarsat
data signal (112 resp. 144 bit, 400 baud, biphase
L-phase modulated, error test / specified according
to Cospas/Sarsat C/S T.001 October 1999)
Bearable kinds of modulation:
A3E, F3E, A2X (ELT-modulation); bearing largely
independent of modulation.
Polarisation
Vertical
Error of polarisation
≤
5° at 60° field vector rotation
Garbling cone
Ca. 30° to the vertical
Time of response: (2)
≤
50 ms (with sufficient receiving field strength)
LC-graphic display
128x64 dots, supertwist /transflective, extended
range of temperature, dark-blue display on yellow-
green background, lit up. Free adjustable
(exponential) dimming of brightness
Supply voltage range
12 V to 35 V DC
Current consumption
LCD-backlight Off:
max. 350 mA (12 V DC) / 200 mA (24 V DC)
LCD-backlight 100 %:
max. 600 mA (12 V DC) / 300 mA (24 V DC)
Note
(1) Undisturbed wave field and sufficient field strength proposed. Measuring by changing the angle of
incidence , the bearing antenna rotates on a revolving table in order to eliminate environment
influences on bearing result.
(2) Very weak signals can considerably increase the time of response!
