The problem with the some European chains is that they have four-digit
GRPs . Therefore, the standard 2000C and maybe others are useless.

This would be a sky wave only signal as I recall from the navy.
So I have g3plx LORAN software and will look to see what I might get here on
the east coast.
Suspect the Canadian chains will go very quic
Is Loran C used with GPS to help make land surveying more accurate?
I thought I read something about using both systems together.

Hello !
Before you throw away your Loran Receivers, have you checked what will
happen with the Canadian Transmitter Chains ?
Would it be possible with better antennas to receive signals from other
countries ?
Would be interested in hearing your input on these ideas !
Thanks !

Hi Joe - Thanks for the good info.
I would like a back rom. Thanks, John K1AE

Hi Robert,
High performance - for me - is 'navigation grade' wrt intertial systems.
Your terminology is somewhat strange to me. 'IN' is that short for
INertial or Inertial Navigation?
There are (used to be) two basic types of intertial navigation systems;
platform systems, where a number of gimba

Hi Bjorn,
This depends on what you call high performance. The normal definition of "high
performance" in relation to IN is low drift with time. Even "cheap" fibre optic
gyro based IN platforms can perform as well as the early airline standard
mecanical units. GPS does not provide attitude or hea
I noticed a glitch at about 0100Z on 11/5/09 with a Fury. Unit has been
tracking within +-10ns for many months, and then suddenly jumped to
-40ns or so and recovered. Not sure if it lost lock or was in holdover.
I wasn't monitoring it with GPScon prior to the event (I had rebooted
the vm tha
I don't remember what day it was but last week I looked at my TAC32 program
and noticed it had lost lock. It showed no satellites tracked. I restarted
TAC32 and all was well. I use a Motorola Oncore and thought it might be
something to do with daylight saving time changing.

On the other hand... With GPS-aiding its argued that high performance
INS-systems are not needed. The same performance will be reached with a
low cost GPS and a mid to low performance inertial system. So I doubt we
will have low cost high performance intertial sensors anytime soon.

about 1900Z)?
(no need to reply if your GPS receivers kept ticking; I'm just
looking here for reports of any signal or tracking anomaly at
the time in question)

A friend of mine is looking for a suitable replacement for the

Correct,
They are already at a price and size where they are making it onto light
aircraft. An IN platform is life cycle cost competitive with a mechanical
vertical/directional gyro pair and adding navigation is "just" (cheap apart
from the RTCA DO-178 assurance) software.
