2 RINEX 发展历程
RINEX 格式由瑞士伯尔尼大学天文学院的 Werner Gurtner 于 1989 年提出。在当时，提出该格式的 目的是为了能够综合处理在 EUREF89（欧洲一项大规模的 GPS 联测项目）中所采集的 GPS 数据。该项目 采用了来自 4 个不同厂商共 60 多台 GPS 接收机。到目前为止 RINEX 共经历了三个版本：RINEX 第一版， 第二版和第三版。 2.1 RINEX第一版
③Wuhan University, Wu Han 430079）
Abstract: With the modernization of GPS and GLONASS, the developing of GALILEO and the application of SBAS, the positioning accuracy and reliability will be greatly improved by use of the combined data of these systems. In order to adapt for the new frequencies and observation types, a new RINEX version 3.00 was developed based on RINEX 2.The paper mainly discusses the difference of RINEX 3.00 and RINEX 2.10 and simply analyzes the application of RINEX 3.00. Key words: RINEX 3.00；GPS；GLONASS；GALIELO；SBAS

Each connection can take two independent conductors.GV3GV3 circuit breakers feature connection by BTR screws (hexagon socket head), tightened using a n° 4 Allen key.This type of connection uses the Ever Link ® system with creep compensation (1) (Schneider Electric patent).This technique makes it possible to achieve accurate and durable tightening torque, in order to avoid cable creep.GV3 circuit breakers are also available with connection by lugs. This type of connection meets the requirements of certain Asian markets and is suitable for applications subject to strong vibration, such as railway transport.GV7GV7 circuit breakers: with connection by screw clamp terminals (for bars and lugs) and by clip-on connectors.OperationControl is manual and local when the motor circuit breaker is used on its own.Control is automatic and remote when it is associated with a contactor.GV2 ME and GV3 ME80Pushbutton control.Energisation is controlled manually by operating the Start button “I” 1.De-energisation is controlled manually by operating the Stop button “O” 2, or automatically by the thermal-magnetic protection elements or by a voltage trip attachment.GV2 P , GV3 P and GV7 Rb Control by rotary knob: for GV2 P and GV3 P b Control by rocker lever: for GV7 R.Energisation is controlled manually by moving the knob or rocker lever to position “I” 1.De-energisation is controlled manually by moving the knob or rocker lever to position “O” 2.De-energisation due to a fault automatically places the knob or rocker lever in the “Trip” position 3.Re-energisation is possible only after having returned the knob or rocker lever to position “O”.(1) Creep: normal crushing phenomenon of copper conductors, that is accentuated over time.GV2 MEwith screw clamp terminals124D F 526134.t i fGV2 MEwith spring terminals connections124D F 526135.t i fGV3 P1324D F 526136.t ifGV2 P1342D F 526137.t i fGV7 R132D F 526138.t i f。

All cables are individually serialized, be sure to write down the cable serial number for future reference.• The terminated fiber ends (the broken out fibers plus connectors) however are fragile, and these must be protected during the installation process.• Leave the protective tube and sock around the fiber tails and connectors in place during hoisting and securing the cable. Remove this only just prior to making the final connections to the Junction box.• DO NOT BEND THE FIBER ENDS (in the furcation tubes) TIGHTER THAN 1.2" (30mm) BEND RADIUS ELSE THEREIS A RISK OF BREAKING THE GLASS FIBERS.• Be sure that the lace up ends and fiber connectors are not damaged by attachment of a hoisting grip or during the hoisting process. Attach a hoisting grip on the jacketed cable no less than 6" below the fiber breakout point. If a hoisting grip is not easily attached, use a simple line attached below the fiber break-out point (i.e. at the cable outer jacket). Prevent the fiber tails (in protective tube) at the cable end from undue movement during hoisting by securing the protective tube (with outer sock) to the hoisting line.• During hoisting ensure that there is a free path and that the cable, and especially the fiber ends, will not be snagged on tower members or other obstacles.• Installation temperature range is -22F to 158F(-30C to +70C).• Minimum cable bend radii can be found in this document or on-line.• Maximum cable tensile load can be found in this document or on-line.• CommScope Lace-Up Hoisting Grip 19256B-Crequired for all installations.• Maximum hanger spacing 3ft (0.9m) - 4ft (1.2m) Hybrid Fiber Cables weigh more than traditional coaxial cables. Be sure to follow proper hoistingand attachment procedures.!isopropyl alcohol), and by applying medium pressure, first wipe against wet area and then onto dry area to clean potential residue from end face. Clean connector ferrule inside adapter by inserting lightly moistened cleaning stick with fiber optic cleaning solution (or >91% isopropyl alcohol) inside the adapter until contact is made with connector on opposite end. Rotate cleaning stick with medium pressure in one circular motion as it is pulled away from the adapter. Repeat process using dry cleaning stick.Caution: Signal strength will be affected if end and sides of ferrule are not thoroughly cleaned. Discard cleaningClean adapter by inserting adapter cleaning stick (or fiber adapter sleeve brush) moistened with fiber optic cleaning solution (or >91% isopropyl alcohol) inside the adapter and gently pull out with twisting motion. Repeat process with a dry cleaning stick.Caution: Do not try to clean adapter with a standard pipe cleaner. The sleeve inner diameter of LC adapters is too small. Do not try to clean the adapter with cleaning stick if a connector is mounted in one side. Discard cleaning sticks after each use.Clean Tip of FerruleWhile holding the protection tube straight pull the tube away from cable.Device designed for cleaning the ferrule end faces of LC connectorsOpen guide cap, insert LC connector into guide, push the outer shell to start cleaning the LC connector interface, a "click" sound indicates end of a cleaning process, repeat, close cap immediately after use.Caution: Be careful not to slant LC connector while inserting into the Guide cap.

Perfect Core Alignment 2. Physical Contact3. Pristine Connector InterfaceToday’s connector design and production techniques have eliminated most of the challenges to achieving core alignment and physical contact. What remains challenging is maintaining a pristine end-face. As a result, CONTAMINATION is the #1 reason for troubleshooting optical networks.Implementing the process of cleaning and inspecting before mating can reduce the time spent troubleshooting, optimize signal performance and prevent damage.InspectingScan to view videoOVP Junction Box: RCMDC-4010-PF-48M40 gland with 3 holes1-1/2 Conduit Fitting DFJ-4S Fiber only JumpersOVP Junction Box Wiring: RCMDC-4010-PF-48Connectthis rowConnectthis row3 in Drawing shown with Qty 1: HFT606-24S37 series trunk and Qty 3: HFA412-4S-39 series jumpersOVP Junction Box: RNSNDC-7771-PF-488 129OVP Junction Box Wiring: RNSNDC-4010-PF-48Connectthis rowConnectthis rowJumperbottomports.5 in Drawing shown with Qty 1: HFT606-24S37 series trunk and Qty 3: HFA412-4S-39 series jumpersExcess Cable ManagementIf length of cable installed needs to be adjusted you can split the cable at the BBU end using the process below and then coiling the excess fiber subunits in a storage box.
