## EROS satellite operations activities

**Ground station operations**
**19x7 operations schedule; 24x7 capable**
**X-band image data reception**
**S-Band TT&C communications**
**Active satellite data reception and processing missions**
**Landsat 5 Thematic Mapper (TM)**
**Landsat 7 Enhanced Thematic Mapper (ETM+)**
**1 Km AVHRR**
**Landsat 5 and 7 satellite operations**
**Mission Operations Centers (MOCs) located in Maryland**

## Landsat Mission 

**Ensure collection of consistently calibrated moderate resolution Earth science imagery**
**Provide long term, repetitive observations of the Earth’s land mass, coastal boundaries, and coral reefs**
**Detect and characterize natural and human induced change**
**Support applications in:**
**Agriculture**
**Geology**
**Resource management**
**Mapping**
**Environmental monitoring and research**

## EROS Supports the Landsat Program Objectives

**Maximize acquisition of global cloud-free Landsat observations**
**Populate U.S. archive to support global change science**
**Distribute products at cost of fulfilling user requests**
**Promote use of Landsat data for land remote sensing research and applications**
**Establish and operate a global network of international cooperators**
**Satisfy national and international Landsat science data requirements**
**Support the USGS Emergency Response Program within the constraints of the Landsat system**

## Landsat 5 International Cooperator Network

## Landsat 7 International Cooperator Network

## NASA / USGS LDCM Responsibilities

**NASA & USGS share responsibility for LDCM mission objectives **
**NASA will:**
**Acquire space segment, mission operations capabilities, launch services;**
**Perform overall mission systems engineering and integration;**
**Manage the LDCM observatory early on-orbit operations from launch through on-orbit acceptance; and**
**Transition mission operations capabilities and observatory operational and maintenance responsibility to USGS, following on-orbit acceptance. **
**USGS will:**
**Acquire and operate the LDCM ground network, data archive, processing, and distribution systems;**
**Acquire and operate LDCM data collection scheduling capabilities;**
**Perform ground system integration and support overall mission integration;**
**Operate the LDCM observatory following on-orbit acceptance; and throughout the life of the mission.**

## USGS LDCM Organization

## LDCM Ground System Major Requirements

**Perform mission operations including data collection scheduling**
**Ingest and archive 400 WRS-2 scenes / day to support observatory ops**
**Make data available for search and order within 24 hours**
**Provide “standard”, orthorectified data products within 24 hours of observation – for data with acceptable quality and cloud cover levels**
**Provide “user specified” data products**
**Ensure LDCM data are calibrated consistently with data from previous Landsat missions**
**Distribute LDCM data products on a nondiscriminatory basis and at a price no greater than the incremental cost of fulfilling a user request**
