CENAMEP AIP: Time and Frequency Laboratory current status
Raul Fernando Solis Betancur
2002 - April: Acquisition of the two Cesium clocks.
2003 - October: Starting of the report to the BIPM and the beginning of the UTC(CNMP).
2005 - December: Incorporation to the common view system started by NORAMED.
2006 - August: First CMC included in the BIPM database.
From 2007 to 2009: Time dissemination services (Voice, Web Clock and NTP).
2009 - February: Declaration of the Time and Frequency National Standards based in the atomics clocks of the CENAMEP.
2009 - December: Implementation of the phase measurement system for the local comparison.
2010 - February: Beginning of the monthly report to the BIPM about local comparison.
2010 - June: Declaration of the UTC(CNMP) as the Official Time of the governmental institutions.
2011 - March: New UTC(CNMP) based in the master clock and the Phase and Frequency Offset Generator.
2011 - October: New CMC included in the BIPM database.
2012 - January: Participation in the pilot project called rapid UTC, the UTCr.
Raul F. Solis B. Electronic Engineer. Since May 2006.
Luis M. Mojica O. Electronic Engineer. Since May 2008.
Actually two metrologists are working in the Time and Frequency Metrology and the Radiofrequency and Microwave Metrology.
Michael Lombardi – NIST (July 2005 and July 2011).
Dr. Jean Simon Boulanger – NRC (September 2005).
Dr. José Mauricio López – CENAM (October 2007 and November 2008).
Dr. Ricardo José de Carvalho – ONRJ (August 2010).
Actually is separated in three laboratories (only his quality system) meanwhile the new building is constructed (2014):
Two low performance Cesium clocks.
DC batteries, UPS and power generator (backup for 3 days)
TTS-2 and SIMTFN System.
Phase and Frequency Offset Generator with the master clock for UTC and SIMT local realization.
UTC (Circular T CCTF-K001.UTC since October 2003). World key comparison.
SIMTFN (and the SIMT) since December 2005. Regional comparison.
Phase measurement system since December 2009. Local comparison.
Data since 2010/04/23 to 2012/07/31.
Data since 2010/02/3 to 2012/08/30.
Data since 2012/01/30 to 2012/08/30.
Two universal counters.
Time and Frequency Processing Card.
Two optical tachometer.
Two signal generators.
Included CMC in the Time and Frequency area:
In 2011, the original first CMC were evaluated for his vitality.
Services accredited in 2007:
Funding cuts and bureaucratic problems caused the suspension of the evaluation in 2012. For this reason we lost the accreditation.
The laboratory transfer his knowledge with courses and trainings:
Two NTP server synchronized to the 1 PPS with a 10 MHz signal for backup.
One Web server synchronized with the NTP server.
Three time server by voice synchronized with the NTP server and the 1 PPS from the UTC(CNMP).
Near of 640 000 visits since 2007 to December 2011.
18,5% of the user not use Java.
5713 visits were from smart phones.
The countries with more visits (in order of visits): Colombia, Canada, United States, Spain, Venezuela and Mexico.
Analog access calling: (+507) 517-3201, 517-3202 and 517-3203.
Three systems were developed by the CENAM based in a own project.
The system is a desktop pc, a software program that control the sound files and the time, a NTP client program and the 1PPS signal to keep running the hour
Near of 5400 callings since March 2009 to December 2011.
35 (government and private) institutions use the service.
Near of 7,4 millions of synchronization request each 5 minutes (since 2009 to December 2011).
Financial companies, governmental organism and logistic companies generated the major of the request.
Only 2 cesium clocks (10 years).
TTS-2 had 10 years of continued working. The TTS-2 is discontinued.
Physical space and electrical capabilities are limited.
The accreditations of the past review services were loss.
Only 2 people to 5 laboratories limit the time for investigation and development of new methods, standards and improvements.
Fully automation of the report process to the BIPM (monthly and weekly files).
With the new cesium clock (maybe the arrival is in December or January) we need to update the software to ensure the comparison of the three clocks and their traceability.
The CENAMEP Time Scale.
Remote calibration of clocks and oscillators.
New time and frequency dissemination services to the electrical and telecommunication companies.
A new national law about the Official Time for Panama (the actual law only cover the government institutions).
