Description: The Micon-GHS clock is an accurate portable clock designed for mobile observation, featuring intelligent functionalities. "Micon" is an abbreviation for "Microcomputer" in Japanese. The clock operates by referencing GPS (Global Positioning System) signals, enabling it to achieve timing accuracy comparable to atomic clocks. An onboard microchip (PIC16F873) allows for on-demand monitoring of geodesic information, such as longitude and latitude. It also provides real-time displays of various astronomical times, including apparent solar time, Greenwich sidereal time, local sidereal time, and the hour angle of the Polar Star. The onboard devices operate on a 5 V DC supply, with a DC-DC converter that steps down from 12 V DC to 5 V DC (1.5 W) for efficient power supply, allowing connection to a car battery via the cigar lighter.
Specifications of the Micon-GHS clock (version 2.1) include:
- Voltage of power supply: 10 V DC to 18 V DC
- Maximum power consumption: 1.5 W
- Timing synchronization accuracy: within 500 ns
- LED device response delay: approximately 40 microseconds
- Time signal output methods: LED flashers, two-line 7-segment LED display, speaker tone, line output
- Minute signal notifications: LED flashers, speaker tone, line output
- Timing information display: Year, Month, Date, Hour, Minute, Second (UTC synchronized)
- Geodesic information display: Longitude, Latitude, Height of receiver antenna, Height of Geoid, Number of GPS satellites acquired, HDOP value, GPS positioning condition
- Positioning accuracy: within 10 m horizontally, with a vertical error of a few 10 m
- Astronomical time display: Apparent solar time, Greenwich sidereal time, Local sidereal time, Hour angle of the Polar Star, with an accuracy of within 3 minutes
- Serial communications: Supports a serial link between the GPS receiver "Jupiter" and a PC, with compatible software "Satk" available for this connection
- Automatic functions: Upon power-on, minute signal adjustments are automatically detected, as well as the reset of intercalary inserted seconds and the rollover of GPS week numbers.
The Micon-GHS clock is a sophisticated piece of hardware that requires a certain level of electrical circuit knowledge and experience for assembly. Building the clock solely from the circuit diagram may be challenging, as it necessitates exclusive pre-programmed PIC chips like [GHS-2] and [GHS-3]. A "Do-it-yourself kit for the Micon-GHS clock" is available, courtesy of the editorial desk of "Tenmon-Guide" and "Geshiro-kumikikou." It is important to note that the GPS receiver "Jupiter" is not included in this DIY kit. The kit contains essential electronic components and a printed circuit board, but does not include the metal case shown in the accompanying photograph. The DIY kit provides the minimum set of electronic devices required for basic operation, emphasizing the DIY spirit, which allows for numerous construction stages to be completed by the user. The kit does not include the brown connector linked to the receiver, lead wires, or the GPS receiver itself, which must be purchased separately from a store or website.
To complete the assembly, connect the finished Micon-GHS clock to the GPS receiver "Jupiter," and attach the antenna to "Jupiter," ensuring the antenna is positioned in an unobstructed area. The synchronization process will take approximately 5 to 10 minutes after powering on the device. Once synchronization is achieved, the message "UTC sync OK" will appear on the LCD display. Upon reaching the final step, geodesic information such as longitude and latitude will be displayed.The Micon-GHS clock is a very accurate handy clock for mobile observation with some intelligent facilities. `Note that "Micon" is a short form for "Microcomputer" in Japanese. `The clock was operated by referring the GPS (Global Positioning System) signal, so that it can attain the accurate timing near as the atomic clock operates.
