System Interface Products (SIP)
What good is precise frequency control if you still have errors from poor phase noise performance?
The Orbital GPS Disciplined Oscillator provides great phase noise along with the advantages of GPS frequency stability. The result is the fastest possible reset upon loss of signal, the fastest possible system wide signal acquisition, zero drift, and the lowest BER due to phase noise. The GPO also contains its own ovenized oscillator that will continue to provide an accurate clock should the GPS satellite signal be lost. The GPO provides individually programmable output levels on two isolated ports so that the output reference signal level can be adjusted to your precise needs.
In addition, the GPO integrates seamlessly with other Orbital SIP products, such as our Mux/Tees, our 10 MHz Splitters, Combiners, Attenuators, Redundant Power Modules, TTL switches, and Thru/Tees. The GPO is plug and play and can retrofit to any existing oscillator.
All of these can be incorporated in our Rackmount products and Controllers along with our C, X, Ku, and Ka band BDCs to provide any band, anytime, anywhere.
Featuring an ovenized oscillator (OCXO), the GPO - GPS Disciplined Oscillator has been designed specifically for the satellite industry. Its sturdy case, allodyned finish, small size and back-o-rack mounting system make it both enduring and easy to use. The Murray-style connectors guarantee the best possible connections for the life of the product.
System Interface Products (SIP), fit between the Outdoor LNB's or transmitters, (ODU),
and the Indoor receivers and modems (IDU).
Quiet, Stable, Pure, and Enduring
Orbital Research's GPS Disciplined Oscillator (OCXO) is designed for low phase noise with exact frequency control and the ability to have all your locations exactly on frequency. We focus on frequency, not timing, for the GPS. This means low phase noise performance of the Oscillator for superior BER, EVM and much faster acquisition times.
The Orbital Research GPO can be used alone or combined with our other products such as the MT25/40 - Mux/Tee or SP10 – 10MHz Splitter. By using the GPO at all your sites, you can be assured that they are all locked, within tolerances, to the GPS Cesium reference.
If the Satellite signal is lost, the GPO will still have a great Oscillator with good stability and phase noise.
GPO Features
Ovenized Oscillator (OCXO)
- Low phase noise -140 dBc/Hz @ 1 kHz
- High output level for service as master system oscillator
- Sine wave purity, filtered low harmonic content
Functional
- Will operate with LNBs, BDCs, VSATs, BUCs, and Modems Variable attenuators on each output
- LED (through gasket) indicators for loss of lock, hardware failure or output level (optional)
Structural
- Machined from solid aluminum billet for strength and stability
- Allodyne finish for corrosion protection and excellent RF shielding/grounding
- 'Back O Rack' mounting for ease of installation and lead dress (Reduces the mess of cables at the back of the rack and provides stability for cables)
- Connectors are 'O' ring sealed for weather resistant operation
Flexible Solutions
An Orbital GPO 10 MHz OCXO Oscillator seamlessly integrates with other Orbital SIP components such as Mux/Tees, 10 MHz Splitters, Combiners, Dividers, etc, minimizing insertion loss, maximizing port to port isolation, matching impedances, and giving a choice of connectors to provide ease of installation.
Made for Professional Use, Made for Satellite
Orbital Systems Interface Products are made specifically for the satellite industry, and are designed for professional and industrial quality systems. Orbital SIP products are built for rack mounting, and for use indoors or out.

 Using a Hi Power Thru Tee to power a BUC |
Modem has DC power, but not enough to power my new BUC. |
| 4 Way Combiner with 10 MHz Oscillator and Hi Power DC insert. |
I want to lock several modems to a single 10 MHz Oscillator, and insert high power DC to my BUC. |
| Orbital 2-way Combiner using 10 MHz from one of the modems and Hi Power Mux/Tee to insert DC power |
I have a pair of modems, one of which provides a 10 MHz reference, but I don't have enough power from my modem for my new high power BUC. |
| Orbital Combiner/Divider stripping out the 10MHz from only one of two modems |
I have a pair of modems and I need to use the 10 MHz reference from one of them and split it. I need to take the L-Band signal from both modems and combine it with the 10 MHz reference. Now I need to insert DC power for a pair of high power BUCS. |
| Orbital Combiner/Divider using a MOS 10 MHz Oscillator |
I need to combine the L-Band signals from a pair of modems with an common, external 10 MHz source, and insert power to a pair of high power BUCs. |
| Using an Orbital Hi Power Thru Tee to circumvent a divider or switch |
My modem does not have sufficient DC to power my BUCs, and I can't switch DC power to the BUC, what to do? |
| Horizontal/Vertical Polarity 1 for 2 Redundant System |
We need a system that will provide us with both horizontal and vertical polarities at Ku Band. In addition, the system must offer 1 for 2 redundancy. |
