## Body

### Overview and Classification
The I-1K is classified as a spacecraft model and functions as a specific type of spacecraft bus. A spacecraft bus is the general model on which multiple-production spacecraft are often based; it constitutes the infrastructure of a spacecraft, usually providing locations for the payload. The payload typically consists of space experiments or instruments. In the context of the I-1K, this bus acts as the service module section of the spacecraft. It is distinct within the field as an Indian satellite bus, with a country of origin listed as India.

### Technical Specifications
The I-1K is defined by specific physical and mass constraints. The bus has a dry weight of 500 kilograms. Regarding its payload capabilities, the I-1K is designed to accommodate a payload mass of 100 kilograms. The physical dimensions of the bus are precise:
- **Width:** 1.476 meters
- **Height:** 1.530 meters
- **Length:** 1.505 meters

These measurements define the volume envelope available for the integration of the spacecraft's subsystems and associated payloads.

### Development and Manufacturing
The development of the I-1K is attributed to the Indian Space Research Organisation (ISRO). The manufacturing responsibilities are held by Antrix Corporation. The entity is also recognized by several aliases, including INSAT-1000, I-1000, and I-1-K, which may appear in technical documentation or references.

### Documentation and Identifiers
Information regarding the I-1K is documented in various external databases and knowledge repositories. The entity possesses a Freebase ID of /m/0_1jjxr. On Wikipedia, the article covering the bus is titled "I-1K" and is available in four languages: English, Galician, Hindi, and Tamil. Technical specifications regarding mass and dimensions are sourced from official documentation, such as the I-1K specification sheet hosted by Antrix Corporation.
