Cause Identified for Pseudorange Error from New GPS Satellite SVN49
-->The gps kids watch Wing and its contractors have traced the cause of pseudorange errors on L1 and L2 broadcast by
the newest gps kids watch satellite, SVN49, to the manner in which the L5 signal demonstration payload was added to the
satellite. Signal leakage between the two input ports of the antenna coupler network for the satellite’s array of
12 helical antenna elements, reflected from the L5 filter and then transmitted, creates a second signal with a
delay of approximately 30 nanoseconds, and the appearance of a multipath component. While testing an adjustment to
the signal-in-space to minimize the effect of the problem on receiver navigation solutions on Earth, the gps kids watch Wing
is interested in hearing from manufacturers and the user community concerning the different impacts of SVN49
signals on the wide range products and applications in operation, before reaching a final decision on what to do
with the satellite prior to setting it healthy.
