C/A (L1) and M-Code (L1/L2)
Time Code Generator / Frequency Generator / Network Time Server
Product Description
The ORCA Technologies TimeTraveler is a rugged C/A or M-Code GPS Synchronized portable master clock that can easily be transported to locations where no synchronization or UTC traceable time and frequency sources are available. The TimeTraveler utilizes a high performance rubidium frequency standard as its internal clock. Prior to deployment the TimeTraveler requires several days of synchronization from GPS to properly discipline the internal rubidium frequency standard in order to meet the high performance requirements of better than +/- 15 milliseconds over a period of one (1) year with no external synchronization.
The TimeTraveler can be configured with one or two high performance Lithium Iron Phosphate batteries. Because ORCA utilizes a “Low Power Mode” of operation while running on batteries this allows our unit to maintain precision time and operation of the rubidium frequency standard in excess of 20 hours. For those situations where a user requires extended battery operation beyond 20 hours, ORCA Technologies has designed an external Battery Pack that can be used in conjunction with the TimeTraveler. These battery packs can be transported separately, charged independently, swapped as needed, and combined to provide a wide range of run times.
The FAA has restricted transportation and use of some batteries on commercial aircraft to a maximum 100 Watt Hour specification. The TimeTraveler falls within these guidelines through the use of a single battery providing 10 hours of run time under “Low Power Mode”. On long flights or operations where extended battery run time is required, ORCA Tech has designed a unique battery swap system where fresh batteries can be installed as needed without affecting the operation of the TimeTraveler. As an added bonus our TimeTraveler batteries can be charged during flight or travel from any available aircraft seat chargers, airport charging stations or any other AC power source.
The TimeTraveler comes standard with a variety of the most popular time and frequency outputs. It doesn’t matter where or when you go, your ORCA Tech precision time and frequency system will be ready with the outputs you need. For a list of these signals please review the product specifications. Custom outputs are available too!
Setup is easy. Prior to leaving for your destination select the “Low Power Mode”. Once AC power has been removed your Time Traveler will operate off the internal batteries. Once AC power has been reestablished or “Low Power Mode” has been disabled, full function of the TimeTraveler including the availability of all the output signals will resume.
Features
ORCA Tech has taken into consideration several very important features.
Modularity
- The TFEP or Time and Frequency Electronics Package is self-contained. If for any reason the TFEP needs to be handled separately or removed from the TimeTraveler the enclosure is secured via 4 twist screws.
- The batteries are also self-contained in their own enclosure and are “hot swappable”. Although the enclosure cannot be removed from the TimeTraveler an easy access lid to the battery compartment has been designed. Removal of the lid allows for easy battery replacement.
Shock and Vibration
- The TimeTraveler is housed in a Pelican Model 1520 case and has been designed to meet the MILSPEC shock and vibration performance specifications of MS-910, MS-901D and MS-461F. The internal timing circuitry has shock mounts to further protect critical components.
