Page 9: General Information
DOC 6501_Release V ATS-6501 Users Guide 1 General Information Introduction The ATS-6501 Tflex is a state-of-the-art GPS Disciplined time and frequency reference. It utilizes an internal rubidium (Rb) atomic clock and low noise synthesizer (LNS) in conjunction with GPS measurements to provide outputs that are characterized by the short-term stability of the atomic clock and the long-term stability of the GPS constellation.
Page 10 Option F (Front Panel Memory Card): Provides access to the unit’s non-volatile memory via the front panel. This option allows users to perform a complete software upgrade in the field without returning the unit to Microsemi. Additionally, the unit can be declassified by simply removing the flash card from the system.
Page 11 TSC-4340AM-8M: 1 U fiber expansion chassis with one multimode mode input and 8 multi- mode outputs. Notes: The correct Microsemi part number is constructed by appending the desired options to the base model in alphabetical order. None of the options are mutually exclusive so users can select as many options as desired.
Page 12: Installation
DOC 6501_Release V ATS-6501 Users Guide 2 Installation The ATS-6501 provides a number of features which may require additional setup and this section provides a guideline for the basic setup. After completing this section, the ATS-6501 will produce timing outputs to the coarse calibration accuracies specified in Appendix A. The ATS- 6501 is designed to be quickly and easily integrated with other system components.
Page 13: Communicating With The Ats-6501
DOC 6501_Release V ATS-6501 Users Guide Communicating with the ATS-6501 Operators are capable of communicating with the system through a LAN connection or via one of the USB Ports when using ATS 6501 OP001 USB to Serial cable to access the command port. 2.2.1 DHCP The ATS-6501 runs DHCP by default and will therefore automatically be assigned an IP address if it is connected to a network with a DHCP server.
Page 14: Setting A Static Ip Address
DOC 6501_Release V ATS-6501 Users Guide Note: We recommend that the USB-to-Serial Adapter (94000-115200) is installed in one of the two USB ports when the system is powered on. If not, you may need to power the system down, plug the cable in and re-apply power. The USB/Serial Cables are programmed to provide users access to the command port (94000-115200) or to communicate with a 5071A Cesium Clock (94001-5071A).
Page 15: Firewall Settings
DOC 6501_Release V ATS-6501 Users Guide 2.2.4 Firewall Settings The system IP firewall has a default “allow all” policy. To enable the firewall, the customer needs to create a firewall rules file on the product file system named /mod/etc/firewall.rules. There are example firewall rules files on the product in the directory /usr/tsc/site/firewall. Example rules files may be copied to the correct location and edited on the product using ‘vi’.

Page 18: Figures Figure 1 Antenna Location
DOC 6501_Release V ATS-6501 Users Guide WARNING: An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

Page 45: Antenna Delay Calibration
For applications requiring the highest level of accuracy, the ATS-6501 should be calibrated at Microsemi. This process involves installing the user’s antenna and antenna cable at the factory and comparing the PPS outputs to a system which has a known offset to UTC(USNO). Once the calibration is complete, the antenna delay value is provided to the customer when the unit is delivered to the user.

Because the generation of timing signals requires that events (e.g., clock steering) occur at very specific times, operational precedence is always given to timing tasks.

In this mode, the system uses the user specified settings for position given by settings gps:positioning:manual_position. This is the mode to use if an AUTO survey was done and the RINEX observation file was post-processed to determine a precise position.
Page 186 DOC 6501_Release V ATS-6501 Users Guide Changing the position_period (given by settings gps:positioning:auto_hours) during a survey changes the time at which the survey will complete but does not restart the survey. If the position_period is shortened to a time that is less than the time already elapsed in the current survey then the survey will be stopped and the position of the GPS antenna will be fixed to a static value.

However, moving the output module to a different slot causes the system to configure the module with the default output format until reconfigured by the user.
