GLONASS Time. 2. Generation of System Timescale
GLONASS TIME SCALE DESCRIPTION Definition of System 1. System timescale: GLONASS Time. 2. Generation of system timescale: on the basis of time scales of GLONASS Central Synchronizers (CS). 3. Is the timescale steered to a reference UTC timescale: Yes. a. To which reference timescale: UTC(SU), generated by State Time and Frequency Reference (STFR). b. Whole second offset from reference timescale: 10800 s (03 hrs 00 min 00 s). tGLONASS =UTC (SU ) + 03 hrs 00 min c. Maximum offset (modulo 1s) from reference timescale: 660 ns (probability 0.95) – in 2014; 4 ns (probability 0.95) – in 2020. 4. Corrections to convert from satellite to system timescale: SVs broadcast corrections τn(tb) and γn(tb) in L1, L2 frequency bands for 30-minute segments of prediction interval. a. Type of corrections given; include statement on relativistic corrections: Linear coefficients broadcast in operative part of navigation message for each SV (in accordance with GLONASS ICD). Periodic part of relativistic corrections taking into account the deviation of individual SVs orbits from GLONASS nominal orbits is incorporated in calculation of broadcast corrections to convert from satellite timescale to GLONASS Time. b. Specified accuracy of corrections to system timescale: The accuracy of calculated offset between SV timescale and GLONASS Time – 5,6 ns (rms). c. Location of corrections in broadcast messages: L1/L2 - τn(t b) – line 4, bits 59 – 80 of navigation frame; - γn(t b) - line 3, bits 69 – 79 of navigation frame. d. Equation to correct satellite timescale to system timescale: L1/L2 tGLONASS = t +τ n (tb ) − γ n (tb )( t − tb ) where t - satellite time; τn(t b), γn(tb) - coefficients of frequency/time correction; tb - time of locking frequency/time parameters. -
GPS Operation V1 4.Fm
Operation of the Courtyard CY490 SPG While Connected to the GPS Receiver No part of this document may be transmitted or reproduced in any form or by any means, electronic or mechanical, including photocopy, recording or any information storage and retrieval system, without permission in writing from Courtyard Electronics Limited. Introduction One of the best sources of reference for both frequency and time, is the Global Positioning System. The GPS system only transmits a complete UTC-GPS time message once every 12.5 minutes. So when powering up the GPS receiver it might be best to wait 12.5 minutes before relying on the GPS time. The CY490 SPG uses a 12 channel GPS receiver. As the SPG is powered the GPS receiver begins searching for satellites from which it can get time, frequency and phase information. In a good reception area as many as 12 satellites may be visible. The SPG only requires 3 satellites to be located and fully decoded before it can start using the GPS data. The search for the first 3 satellites can take up to 3 minutes, but is often accomplished in 2. If less than 3 satellites are available, the SPG will not lock to GPS. The number of satellites can be monitored on the first menu and on the remote control program CY490MiniMessage. The CY490MiniMessage gives a graphic view of satellites and provides much information for the user. GPS and television From a GPS receiver, the Master Clock can derive UTC and also add the appropriate time offset and provide corrected local time. -

Exercise 10 ‐ Batteries
WS 2019/2020 Elektrochemie Prof. Petr Novák Exercise 10 ‐ Batteries Assistant: Laura Höltschi ([email protected]) Exercise 1: (a) What are “batteries” (Provide a definition)? Batteries are electrochemical devices which store electrical energy in the form of chemical energy. The electrochemical cells may be connected in series or in parallel, or a combination thereof, to constitute a battery module or battery pack. (b) Batteries are divided in groups such as primary and secondary cells. Characterize both groups (definition) and give 2 examples for both types of cells. What are the advantages and disadvantages of both groups? Provide some applications for both types of cells. Primary cells: Batteries that can only be discharged once and cannot be recharged (irreversible). Examples: Alkaline batteries, primary zinc‐air batteries, some lithium batteries Advantages(+): Long calendar life/low self‐discharge, very robust (large domain of applications) Disadvantages(‐): can only be used once (problem for recycling (trash), expensive) Secondary cells: Batteries that can be charged and discharged multiple times (reversible). Examples: nickel‐cadmium battery, lead‐acid battery, lithium‐ion batteries,… Advantages(+): reusable, low operating costs Disadvantages(‐): often high self‐discharge, domain of application/storage under optimal conditions required, destruction due to depth of discharge, rapid charge or overcharge, high investment costs, often bad cycling stability,… Examples of application domains: Primary cells: constant and small energy extraction over long time periods – watches, data storage units, measurement devices,… Secondary cells: high and permanent (mobile) energy demand (mobile phone, lap‐tops, batteries for cars and electro‐mobility), where there might be a need to recharge multiples times. Exercise 2: An alkaline battery is an example of a primary battery and the reaction shown below is the cell reaction during discharge. -
15 Pecision System Clock Architecture
Pecision System Clock Architecture 15 Pecision System Clock Architecture “Time iz like money, the less we hav ov it teu spare the further we make it go.” Josh Billing Encyclopedia and Proverbial Philosophy of Wit and Humor, 1874 225 Pecision System Clock Architecture Limitations of the Art Over the almost three decades that NTP has evolved, accuracy expectations have improved from 100 ms to less than 1 ms on fast LANs with multiple segments interconnected by switches and less than a few milliseconds on most campus and corporate networks with multiple subnets interconnected by routers. Today the practical expectations with a GPS receiver, PPS signal and precision kernel support are a few microseconds. In principle the ultimate expectations are limited only by the 232-ps resolution of the NTP timestamp format or about the time light travels three inches. Improving accuracy expectations below the PPS regime is proving intricate and tricky. In this chapter we turn to the most ambitious means available to minimize errors in the face of hardware and software not designed for extraordinary timekeeping. First we examine the hardware and software components for a precision system clock and evolve an optimal design. Next we survey timestamping techniques using both hardware, driver and software methods to minimize errors due to media, device and operating system latencies. Finally, we explore the IEEE 1588 Precision Time Protocol (PTP), how it is used in a high speed LAN, and how it and NTP can sail in the same boat. The parting shots section proposes a hardware assisted design which provides performance equivalent to PTP with only minimal modifications to the Unix operating system kernel. -

Date and Time Terms and Definitions
Date and Time Terms and Definitions Date and Time Terms and Definitions Brooks Harris Version 35 2016-05-17 Introduction Many documents describing terms and definitions, sometimes referred to as “vocabulary” or “dictionary”, address the topics of timekeeping. This document collects terms from many sources to help unify terminology and to provide a single reference document that can be cited by documents related to date and time. The basic timekeeping definitions are drawn from ISO 8601, its underlying IEC specifications, the BIPM Brochure (The International System of Units (SI)) and BIPM International vocabulary of metrology (VIM). Especially important are the rules and formulas regarding TAI, UTC, and “civil”, or “local”, time. The international standards that describe these fundamental time scales, the rules and procedures of their maintenance, and methods of application are scattered amongst many documents from several standards bodies using various lexicon. This dispersion makes it difficult to arrive at a clear understanding of the underlying principles and application to interoperable implementations. This document collects and consolidates definitions and descriptions from BIPM, IERS, and ITU-R to clarify implementation. There remain unresolved issues in the art and science of timekeeping, especially regarding “time zones” and the politically driven topic of “local time”. This document does not attempt to resolve those dilemmas but describes the terminology and the current state of the art (at the time of publication) to help guide -
