GPS-MTG GPS Based Master SMPTE Time Code Generator
The GPS-MTG uses the accuracy of the atomic clocks in the Global
Positioning System to generate SMPTE longitudinal time code
matched to UTC, offset to local time or time and date, day-after-day,
month-after-month, year-after-year, unattended, anywhere in the
world. When generated by the GPS-MTG, SMPTE time code becomes
an accurate global real-time clock/calendar, allowing video images separated across the city, state, continent, or globe, to
be simultaneously recorded with the same time and date stamp.
◆ Generates drop frame time code locked to
an external color video (RS-170A) reference.
Continuously monitors satellite time and
date and maintains correct generator time.
◆ Use as precision stand alone SMPTE studio
clock reference to time and control events or
studio automation systems. Operate SMPTE
display devices for accurate time-of-day
readouts, or time/date stamp video images.
◆ RS-232 output with HSIP (Horita Standard
Interface Protocol) data for input to a PC.
MTG Time software is included to preset and
maintain the PC clock/calendar at UTC or
local time using the HSIP data input.
◆ Automatic daylight savings time mode
◆ Front panel LED and video “time code
window” display show a flashing 1-PPS
“GPS locked” indicator for positive visual
indication of active lockup to the GPS system.
◆ “Fail-safe” alarm logic output provides
remote indication of power or video loss or
GPS antenna disconnection.
◆ Manual mode operation with or without GPS
receiver allows manual preset of time and
user bit data.
◆ Extra front panel RCA connector provides
quick and convenient access to time code
output. Rear panel DB-9 connector provides
additional 1-PPS and 1-PPM pulse outputs
for operating studio clock systems.
◆ Optional cable lengths allow up to 300’ of
separation between antenna/receiver and
Master Time Code generator.
GPS-MTG: Includes rugged GPS antenna/
receiver, 50’ GPS-to-MTG cable, 6’ MTG-to-
computer cable, Windows clock software.

GPS and UTC Time
The Global Positioning System (GPS) is a navigation and position-locating system based
on reception from NAVSTAR satellites. GPS receivers provide highly accurate time fixes
anywhere worldwide. GPS system time is a worldwide standard atomic time that is exactly
related to Coordinated Universal Time (UTC or “Greenwich time”). Local time is Greenwich
time offset by hours corresponding to local time zone.
The GPS satellite antenna/receiver provided with Horita GPS/SMPTE time code and video
is a small dome about 4” high by 6” in diameter. It is rugged, sealed against the environ-
ment, and mounts with a standard 3/4” threaded pipe fitting. It comes with a 50’ cable and
is usually installed outdoors on a roof or indoors under a skylight. It does not have to be
oriented in any special manner other than to have a broad view of the sky.
FEATURES
GPT-50 Real-Time GPS Video Titler/Captioner
The GPT-50 adds real-time GPS data to video for
recording or viewing. The video output from the
GPT-50 is the same as the video input plus a caption of
GPS position and other data, depending on input code
format. Works with NTSC and PAL video and RS-232 or
RS-422 serial inputs, in several selectable formats. You
can select from a total of 12 GPS input code formats.
◆ Front panel switches for manual setup of format, display options, and entry of titles to provide
other captions in addition to the GPS data. Two setup screens maintain two independent GPT
setups; 14 line and 7 line (half-size) display sizes; ASCII and HEX display formats for diagnostics.
◆ Independent real-time clock/calendar display for stand-alone time and date stamping.
◆ Dual DB-9 input connectors provide serial input data “loop thru” to additional GPT-50 units for
titling other video sources with the same time and position information.
◆ Operates from an external power source of +9 to +14 v DC. Includes wall mount 9v DC supply.
◆ Desktop size: 1.9” x 5.3” x 3.8” (HxLxW).
◆ Provides selection of the following serial formats: NMEA 0183 sentence $GPGGA
(industry standard) or $GPGLL or $GPRMC.
◆ Trimble ASCII formats: TAIP (Trimble ASCII Interface Protocol); Pathfinder Basic+; TNL 2100/3100
formats RO, R1, KO, K1, XO, X1.
◆ Navstar ASCII Formats: –GPS2D/3D; UTM (Universal Transverse Mercator).
◆ Trimble TSIP Binary Format (Trimble Standard Interface Protocol, formerly TANS): Two-way serial
communication; Uses single-precision latitude/longitude.
