About
A listing of all active and inactive satellites and sensors currently found in Earth's orbit. This data set provides a foundational inventory for understanding space infrastructure and is delivered in a raw state, indicating that initial cleansing and preparation are necessary prior to detailed analysis. This inventory is significant for studies related to global space activity and the operational lifetime of orbiting assets.
Columns
- Name: The specific designation or name of the satellite or sensor. There are 337 unique values recorded, representing 100% of the entries.
- Orbit Type: Defines the type of orbit utilized by the satellite, with the most common being Sun Synchronous (72%) and Geostationary (15%).
- Orbit Height (Km): The altitude of the orbit, measured in kilometres. A specific height, 35786 km, accounts for 5% of the entries.
- Repeat Cycle (days): Indicates the period, in days, required for the satellite to repeat its ground track. Note that 50% of the entries in this column are currently missing data.
- Launched In: The year in which the satellite was put into service. Examples of prominent launch years include 2018 (9%) and 2022 (5%).
- Out of service since: The year the satellite ceased operations. This field has a high percentage (66%) of missing information.
- Organization: The governing body or agency responsible for the satellite. Major organizations include NASA - USA (12%) and ISRO - India (10%).
Distribution
The data is provided in a CSV file format named
AllSatellites.csv, with a file size of 39.02 kB. The data structure includes 7 distinct columns and contains 337 records in total. It is noted that this inventory is raw data and necessitates cleansing. The update frequency for this specific list is expected to be 'Never'.Usage
This inventory is highly suitable for Exploratory Data Analysis, particularly for users new to space-related data sets. It can be applied in studies pertaining to Science and Technology development, focusing specifically on Earth Science applications. Researchers can analyse launch trends and organizational dominance in specific orbit types.
Coverage
The data encompasses satellites within Earth's orbit globally. The temporal scope spans from the earliest recorded launch year through to the latest listed 'Out of service since' year. Data on repeat cycles and out-of-service dates have notable gaps, affecting temporal completeness.
