ITU-R TF.768-2 The ITU Radiocommunication Assembly, considering a) the continuing need in all parts of the world for readily available standard frequency and time reference signals that are internationally coordinated; b) the advantages offered by radio broadcasts of standard time and frequency signals in terms of wide coverage, ease and reliability of reception, achievable level of accuracy as received, and the wide availability of relatively inexpensive receiving equipment; c) that Article 33 of the Radio Regulations (RR) is considering the coordination of the establishment and operation of services of standard-frequency and time-signal dissemination on a worldwide basis; d) that a number of stations are now regularly emitting standard frequencies and time signals in the bands allocated by this Conference and that additional stations provide similar services using other frequency bands; e) that these services operate in accordance with Recommendation ITU-R TF.460 which establishes the internationally coordinated UTC time system; f) that other broadcasts exist which, although designed primarily for other functions such as navigation or communications, emit highly stabilized carrier frequencies and/or precise time signals that can be very useful in time and frequency applications, recommends 1 that, for applications requiring stable and accurate time and frequency reference signals that are traceable to the internationally coordinated UTC system, serious consideration be given to the use of one or more of the broadcast services listed and described in Annex 1; 2 that administrations responsible for the various broadcast services included in Annex 2 make every effort to update the information given whenever changes occur.

  • Synchronizing Time with Dcf77 and Msf60
    SYNCHRONIZING TIME WITH DCF77 AND MSF60 In many of the applications that use the H0420 and Starling programmable audio controllers/players, clock synchronization is a requirement. This is especially the case with the H0420, because it lacks a battery backup for its internal real-time clock —hence, when there is a power drop-out (even for less than a second), the H0420 resets to 1 January 1970 at 00:00 hours. Even with a backup battery for the real-time clock, when the device is used outdoor, you may observe the clock on the H0420 or Starling to deviate from the true time. The reason is that the crystals used for timekeeping are calibrated for use at room temperature. The time that the device resets to after power-up, of 1 January 1970 at 00:00 hours, is the "start of the Unix era". This is a commonly used basis for time keeping in operating systems and embedded devices; see the Wikipedia article in the references. For keeping the time of the H0420/Starling accurate, there are two options: get the time from the network (a typical option for the Starling, as it has a network port), or get the time from some other source, such as a radio signal. This latter option is suitable when no network is available at the location, which is common in outdoor use. This article specifically discusses how to pick up the current "time of the day" from DCF77 signal, but also discusses MSF60. A particular advantages of synchronizing on a time signal radio station is that "daylight saving time" is automatically handled.

This article presents the quasi-delay-insensitive (QDI) early output versions of recently reported indicating asynchronous array multipliers. Delay-insensitive dual-rail encoding is used for data representation and processing, and 4-phase return-to-zero (RTZ) and return-to-one (RTO) handshake protocols are used for data communication. Many QDI array multipliers were realized using a 32/28 nm complementary metal oxide semiconductor (CMOS) technology. Compared to the optimum indicating array multiplier, the proposed optimum early output array multiplier achieves a 6.2% reduction in cycle time and a 7.4% reduction in power-cycle time product (PCTP) with respect to RTZ handshaking, and a 7.6% reduction in cycle time and an 8.8% reduction in PCTP with respect to RTO handshaking without an increase in the area. The simulation results also convey that the RTO handshaking is preferable to the RTZ handshaking for the optimum implementation of QDI array multipliers.

  • RTZ 1.1 Guidelines Ver. 1.8
    RTZ 1.1 Guidelines ver. 1.8 Guidelines for STM 1. General Comments The base RTZ format was contemplated as flexible and easily expandable. That is why the minimum requirements set for it are not burdensome: it is only necessary to provide a route with the route name (routeName in the routeInfo) and a set of (at least two) waypoints (in the waypoints container element). Each waypoint should necessarily be provided with at least geographic coordinates (position). The rest is optional in the RTZ. For STM validation we have extra requirements and following fields became mandatory: vesselVoyage in the routeInfo element routeStatusEnum in the routeInfoEx extension of the routeInfo element. It means that routeInfoEx extension element became mandatory for STM usage as well. The vessel voyage ID is the Unique Identity of a Voyage and should be used exactly specified in the STM MRN format in the RTZ vesselVoyage field, for example for the org name ‘acme’: vesselVoyage="urn:mrn:stm:voyage:id:acme:b6d7b492-ab3c-42f2-8afd-116c3d872f0c" Service providers shall not change UVID of each route received from a ship. IF it is brand new route that Service Provider is going to send to a ship, then UVID field must be filled in, because the UVID field CANNOT be empty. 2. Route Geometry Each route leg is formed as the shortest of all the possible segments within the framework of the set geometry (Great Circle or Rhumb Line) on the terrestrial ellipsoid. The following multiplicities may arise in the process: 1. The GC or RL geometry type, and the ends of the segment are on the opposite poles.
