GPS receiver (Gamin, Eagle etc) to PC interface cables -
GPSy(TM) has extensive documentation on how to create your own
data cables, and if you are handy with a soldering iron (or know
how to use crimp connectors), there are some instructions. |

GPS Receiver Based Frequency Standard - Frequency accuracy
has been a topic of special interest to many amateurs and
experimenters since the early days of radio. Until recently,
the best frequency standard available to most hams was a crystal
oscillator carefully adjusted to zero-beat.... [By Brooks Shera,

- My first two GPSes were both Garmin eTrex models. One was the
original yellow eTrex, and the second was the eTrex Legend which
has more memory, and most importantly, mapping capability.
Neither of these is an aviation GPS, but both can be useful in
the VFR cockpit..... [Stefan Vorketter] |

Inertial-navigation system uses silicon sensors - 16-Sep-04
Issue of EDN A strap-down inertial-navigation system uses
silicon sensors to measure displacement without entailing the
bulk and expense of moving parts or GPS receivers. For example,
a three-axis accelerometer and three angular-rate sensors can
determine the position and velocity of a vehicle such as a robot
or radio-controlled aircraft..... [Design Idea by Tom Niemi,

Three Power Supplies for the Garmin GPS-20 Sensor Board -
Since the GPS-20 is an OEM (Original Equipment Manufacturer)
product it does not come ready to use out of the box. There is
no display, only a 12-pin JST connector that provides two RS-232
compatible serial ports, a One-Pulse-Per-Second (1PPS) output,
and power. There is also a MCX style connector for the antenna
connection..... [Steve Bible] |
