## IOC and FOC Criteria

**Initial Operational Capability**
- All ground segment elements required to operate the satellites have been delivered, tested, and certified ready for operations
**One Satellite operational in **_**two of three**_** orbital planes**
- The EDR attributes associated with those two orbital planes are satisfied
- Sufficient crews are trained to sustain continuous operations at the MMC and SMMC as needed
- Sufficient Engineering resources are in place to support the C3, data recovery and IDPS

**Final Operational Capability**
**One Satellite is operational in **_**all three**_** of the required orbital planes**
- The EDR attributes associated with all three orbital planes are satisfied
- IORD Key Performance Parameters (KPPs) have been met, to include revisit criteria
- Sufficient crews are trained
- Sufficient logistics resources are in place to support C3, data recovery, and the IDPS
- Sufficient C3 and data recovery resources are available

## NPOESS Operational Modes

- Launch and Early Orbit (LEO)
- Calibration and Validation
- Continuous Broadcast Activation
- Normal Operational Mode including Monitoring and Sustainment
- Operational Programming (System Upgrades)
- Selective Data Denial
- Anomalies
- Decommissioning

## NPOESS Operational Mode Change Process

## Space to Ground Communications

- Stored Mission Data (SMD)
- Downlinked via Ka-band to SafetyNetTM Receptors
- NPP will use X-band to Svalbard
- Direct Broadcast Data
**High Rate Data (HRD)**
- Downlinked via X-band at 20 Mbps
- Contains all sensor data at maximum resolution
**Low Rate Data (LRD)**
- Downlinked via L-band at 3.88 Mbps
- Contains Subset of NPOESS Data (Programmable)

## SafetyNetTM Sites by Country

*A key feature of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) is the Northrop Grumman Space Technology *
*patent-pending innovative data routing and retrieval architecture called SafetyNet**TM**.*

## Example of NPOESS LRD Content Flexibility

## NPOESS Constellation Assessment Team (NCAT)

- Chaired by IPO ADO, and convened Quarterly
- Will be established 3 years prior to C-1 launch
- Performs Two Functions:
- Serves as NPOESS Interface to the 14th Air Force Current Launch Schedule Review Board (CLSRB) to ensure NPOESS launch queue requirements are met
- Will monitor and report on the health and status of individual satellites, sensors and systems as well as whole constellation and C3 system once IOC is declared
- Makes Operational Impact Assessments to the IPO SPD
- Makes replenishment recommendations to the IPO SPD
