By offering a defined structural envelope (91 cm × 91 cm), power capability (~1500 W from a solar array), and payload capacity (~300 kg), it enables mission developers to focus on their experiments or instruments rather than redeveloping basic spacecraft subsystems. This standardization reduces development time, cost, and risk, fostering greater access to space for a variety of payloads and supporting the scalability of satellite constellations or technology demonstration missions. ## Notable For - Provides a 91 cm × 91 cm bus footprint, a compact yet versatile form factor for small‑ to medium‑sized spacecraft. - Delivers approximately 1500 watts of electrical power via its solar array, supporting power‑intensive payloads. - Supports an approximate payload mass of 300 kilograms, accommodating a range of experiments and instruments. - Developed by York Space Systems, a U.S.–based manufacturer, contributing to domestic space industrial capability. - Classified both as a spacecraft model instance and a spacecraft bus subclass, reflecting its role in both specific vehicle designs and broader bus architecture. ## Body ### Overview LX-Class is a satellite bus created by York Space Systems. It functions as the service module and structural backbone of a spacecraft, providing locations for payloads such as space experiments or instruments. As a spacecraft bus, it enables the construction of multiple‑production spacecraft by offering a reusable infrastructure. ### Dimensions - Width: 91 centimetres. - Length: 91 centimetres. These measurements define the bus’s external envelope and are sourced from the manufacturer’s documentation. ### Power System The bus incorporates a spacecraft solar array. The array is specified with a qualifier P1114 = 1, indicating a single unit, and an estimated power output of 1500 watts (qualifier P2109 = 1500 Q25236). This power level is intended to support the electrical needs of onboard payloads and subsystems. ### Payload Capacity LX-Class is rated for an approximate payload mass of 300 kilograms, with the qualifier “approximately” (P5102) attached to this figure. This capacity defines the maximum mass of experiments, instruments, or other payloads that can be accommodated. ### Manufacturer and Origin - Manufacturer: York Space Systems. - Country of origin: United States. These facts establish the entity responsible for the bus’s design and production and its national background. ### Classification - Instance of: spacecraft model. - Subclass of: spacecraft bus. The dual classification reflects that LX-Class represents a specific model design while also belonging to the broader category of spacecraft buses, which provide the infrastructure for spacecraft. ### Reference Source All technical details are documented in the manufacturer’s PDF available at https://www.yorkspacesystems.com/_files/ugd/d2c1c3_097cd7bb73f1438abc642b1a32cbfd72.pdf, which is in English. ### Relationships LX-Class is related to the general concept of a spacecraft bus, which is described as the infrastructure of a spacecraft—usually providing locations for the payload (typically space experiments or instruments) and constituting the service module section. This relationship situates LX-Class within the wider context of spacecraft design and production. ## References 1.
