| High Rate Data Transfer - An Optimum Solution |
| |
| The highly efficient Data Link Transmitter |
| (DLT) transmits high rate data gathered |
| on board low earth orbiting satellites |
| to ground stations. |
| The unit performs data formatting, |
| encoding for error correction, X-band generation of an RF modulated |
| signal and parameter monitoring, |
| as well as BIT performance verification. |
| Low power consumption and flexible design, |
| enabling smooth adaptation of the DLT to |
| specific customer requirements, |
| make for ideal, high rate satellite communications. |
| |

| Electronic Ground Support Equipment (EGSE) |
| The EGSE us used for DLT testing, verification and |
| integration. The equipment provides interface |
| emulation to each of the on-board interfaces, |
| such as data source, power supply, |
| antenna and controller. |
| monitoring, as well as BIT performance verification. |
| |
| The EGSE ensures gradual and smooth |
| integration through stepwise connection |
| of the DLT to the on-board system. |
| Functionality and performance are |
| verified at each phase. |
| Built-in standard and |
| specialized test equipment |
| allows full performance analysis. |
| |
| The EGSE's easy to use and responsive |
| Windows-NT based GUI applies |
| the finishing touch to DLT |
| integration. |
