- It was developed and launched by the Indian Space Research Organisation (ISRO), showcasing India’s indigenous space technology capabilities.
- The use of the Polar Satellite Launch Vehicle-XL (PSLV-XL) for its launch demonstrates the maturity of India’s launch vehicle technology.
- Operating in a geostationary transfer orbit (GTO) allows for subsequent orbital adjustments to reach its intended navigation orbit.

## Body
### Launch and Deployment
IRNSS-1E was launched on January 20, 2016, from the Satish Dhawan Space Centre Second Launch Pad. The launch vehicle was a Polar Satellite Launch Vehicle-XL (PSLV-XL), a model of the Indian Polar Satellite Launch Vehicle. The satellite was part of the Indian Space Research Organisation’s (ISRO) efforts to expand the IRNSS constellation.

### Technical Specifications
- **Mass**: 1425 kilograms (as per the source material).
- **Operator**: Indian Space Research Organisation (ISRO), which also owns the satellite.
- **Country of Origin**: India, with references to ISRO’s launch records.
- **Classification**: Navigation satellite, belonging to the IRNSS system.

### Orbit and Operation
IRNSS-1E is placed in a geostationary transfer orbit (GTO) after launch. Its subsequent orbital adjustments are part of the process to position it within the IRNSS constellation for navigation services. The satellite operates as part of the Indian Regional Navigation Satellite System, providing regional navigation coverage.

### Constellation Role
As a member of the IRNSS constellation, IRNSS-1E works alongside other satellites (like IRNSS-1D and IRNSS-1F) to ensure continuous navigation coverage. Its placement in the constellation helps in maintaining the system’s redundancy and reliability for users in India and neighboring regions.
