Tools (14)

• explain_properties

  What every property of a product category means: definition, how it is measured and what goes into the measurement condition, how to use it when selecting, what it is commonly confused with, typical range and related properties. Call this before interpreting specs of an unfamiliar category.

• match_components

  Reverse search over a typed spec layer: pass a category and engineering requirements, get every catalogued item grouped as A (meets all stated requirements), B (fails a named requirement, both figures quoted) or C (could fit, data missing). Verdicts cite the datasheet page. Omit parameters you do not care about. Categories: reaction-wheels, star-trackers, obc-computers, batteries, radios, solar-panels, propulsion, sun-sensors, magnetometers, magnetorquers, imus-gyros, gnss-receivers, eps, deployers, thermal, antennas, sdr-modems, cameras, structures, platforms, ground-stations, sadm, tanks-valves, separation-systems, pointing-mechanisms, test-facilities (environmental test labs — items are companies: test, shaker_min_kn, tvac_min_m, specimen_min_kg, emc_min_m). The answer is compact: group A in full (up to 25), groups B and C — the first 10 with the reason, plus counts and the fields most often unpublished in C; page with group and offset.

• find_alternatives

  Alternatives / second sources / replacements for ONE product: requirements are derived from its own published values (key fields of its class — higher-is-better at least 80 %, lower-is-better at most 120 %, same interface, band or type) and its class is searched without it. Returns the derived requirements, fields not compared, and groups A (meets all), B (fails one), C (data missing). Use when a part has a long lead time, is discontinued or export-restricted. Equal figures do not make a drop-in replacement — interfaces must be confirmed with the manufacturer.

• selection_guide

  How to choose a product of one category, from the catalogue data only: the decisive parameters with real ranges (middle half and full range), which side is better, how many products publish each, what to ask the vendor, and ready match queries. category = "cubesat" gives the list of subsystems a CubeSat is built from with catalogue counts.

• find_suppliers

  Companies whose PRODUCTS meet engineering requirements in one category — "who makes platforms for GEO", "Chinese companies making star trackers better than 10 arcsec", "suppliers of flight-proven reaction wheels". Pass category, optional country and any requirement parameter of match_components (same names and units). Returns companies with their matching products, and how many more companies may fit because the decisive value is not published.

• build_budget

  Engineering budget for a component stack: pass product ids (from the other tools) and your bus voltage, get total mass, total steady-state power, per-item data interfaces, voltage-compatibility verdicts and an honest list of what could NOT be counted because the vendor does not publish it. Use it to assemble and sanity-check a subsystem, e.g. 3-4 reaction wheels for an ADCS.

• get_component_specs

  The typed layer of a category, 10 products per call (page with offset, narrow with ids and keys) — every item with every value (number, canonical unit, bound, measurement condition, datasheet source page, confidence L0/L1) plus the property dictionary grouped by interface port (perf/power/data/mech/thermal/env/supply) — for arbitrary comparison, budgeting or trade studies on your side.

• get_datasheet_digest

  Facts machine-read from a product datasheet, by section (identity, performance, electrical, interfaces, mechanical, thermal, environmental, qualification, lifetime, options, compliance, commercial). Each fact carries unit, condition, the page and a verbatim quote it was verified against (confidence L0) plus a link into the PDF. Use it for what the typed layer does not hold: connectors, protocols, survival temperature, vibration, radiation, heritage, options, export control, lead time. Pass product_id from match_components or a product name.

• search_datasheet_facts

  One fact key across a whole category: which products state it in their datasheets and what value — e.g. connector, data_interface, protocol, survival_temperature, tid_tolerance, flight_heritage, trl, export_control, lead_time, price, design_life. One row per product with page and quote. Reports coverage (how many products of the category have a digested datasheet).

• ask_datasheet

  Ask a product datasheet a question and get the closest excerpts with page numbers (pre-indexed text), or scan ALL datasheets of a category for an exact term (term + category) and get the exact list of products mentioning it with an excerpt each.

• design_stack

  Assemble a whole spacecraft bus from a plain-language task: the service plans the subsystems, matches every item deterministically against the stated requirements, computes the mass/power budget and writes an evidence-bound rationale. Pass fixed = product ids you have already chosen (from match_components or get_datasheet_digest): they stay in their subsystems, are checked against the requirements (selected.fixed, fixed_verdict, fixed_fails) and the rest is assembled around them. LLM-backed and rate-limited (6/min, 30/h anonymous).

• find_data_gaps

  What is missing for a product, a company or a category and where to get it: in_digest (already read from the datasheet — value, page), in_datasheet_text (the datasheet mentions it — page, excerpt), not_in_datasheet (ask the vendor), no_datasheet (ask the vendor for a datasheet). For vendors: what to publish; for buyers: what to ask.

• ask_console

  Plain-language engineering question over the whole platform, answered by platform rules without any external model: selection by requirements, values of a property across a class, companies by capability and country, launch windows, term definitions. Returns a short answer plus data blocks (candidates A/B/C, values, companies, launches). Use when the question does not map cleanly onto one structured tool.

• check_fit

  Check whether a set of products docks together, by the interface template of each product type: deployer and CubeSat structure form factor and satellite mass, separation system and spacecraft mass, solar panel size and EPS solar input (Voc/Vmp, power), battery and EPS, EPS output rails or the unregulated bus against each unit supply range, EPS charge current against the battery limit, satellite envelope against the deployer envelope for its form factor, on-board computer against unit data interfaces, board stack format, free volume, radio against antenna and ground station (frequency, band, connector, protocol and modulation), antenna against ground station polarization, GNSS receiver signals against the GNSS antenna band, magnetorquer coil current against the driver channel, PPU output power against the electric thruster, array drive against panel power, propulsion propellant against tank media, steady power budget. Verdicts fits / conflict / check / unknown, plus ask_vendor: exactly
