Satellite Controlled Nixie Tube Clock (NixiSat)
40cm L x 16cm H; NixiSat is suitable for display in a
or your residence. The 100mm tall Nixie Tubes are viewable
from a great distance.
NixiSat is controlled by an integrated GPS satellite receiver module,
decoding transmissions from 28 US government defense satellites
The NAVigation Satellite Timing and Ranging
(NAVSTAR) system was
developed to meet the military needs of the United States Department of
The extraordinary ranging accuracy of GPS is the result of an
cesium clock reference transmitted by the ground based segments of
NixiSat takes advantage of the NAVSTAR precision timekeeping system
to deliver a clock with "beyond question"
There are no other satellite
controlled clocks offering a comparable level of performance, and
features at a hobby kit price. NixiSat uses a Direct Drive Nixie Tube
No multiplexing was used. Although more complex; Direct Drive offers
the distinct advantages of a brighter digit display, and extended (10+
yr) tube life.
This clock was developed as a partnering project with John
Miktuk. An engineering team approach will always deliver a
product to the customer.
The clock base is offered in a choice of two different woods:
Cherry, and American Walnut. Please click here for example images: Cherry

of: 1, 15, 30, 60 minutes.
Time can be displayed in 12 or 24 hour format. For 12 hour
a PM indicator is located at the lower left of the
Date can be displayed in either
mm,dd,yy OR dd,mm,yy format. The temperature
can be displayed in degrees F or degrees C with quarter degree
A pleasing soft chime tone
can be enabled to strike at selected intervals, and a choice of chime
styles are provided. The scrolling speed can be varied from slow
to -fast in a range of ten
individual steps. And, each of the features can be separately
disabled from the periodic scrolling cycle. The colon
separating the paired digits can
vary their configuration to upper, lower, or independent. This

NixiSat receives the satellite transmissions using a compact
style 1.5Ghz antenna. Some locations may provide adequate satellite

structure, whereas others will require an externally mounted
The antenna is weatherproof, and includes a 20' coaxial lead in for

In the event of satellite signal loss after successful startup; NixiSat
will continue operation using the high precision 1pps signal pulse from
the GPS receiver.
The lower right colon lamp will extinguish to indicate the clock is
operating from the local precision, then relight when the satellite
has been restored.
If power is lost, a lithium battery will maintain GPS receiver
and quickly resume operation when power is restored. No

The materials used to construct the NixiSat satellite
clock are of the absolute highest quality.
