Teams preparing a HASP proposal/payload are advised to download and read the HASP Student Payload Interface Manual as well as CSBF website postings at https://www.csbf.nasa.gov/docs.html, particularly the FY07 User’s Handbook.  Also of use are the Gondola Design documents at http://www.csbf.nasa.gov/gondoladocs.html.

Student Payload Interface

HASP Payload Interface ManualHASP Student Payload Interface Manual

There are two classes of payload seats available to students on HASP.  The more numerous  “small payload class are generally used for smaller experiments or testing of satellite prototypes.  The “large” payload class is useful for complex, large geometry, or heavy experiments.  The detailed compatibility for each payload class is given below.

Small Student Payloads: 
Total number of Positions availableup to 16
Maximum Weight:3 kg (6.6 lbs)
Maximum Footprint (must include mounting structure):15 cm x 15 cm (approximately 6″x6″)
Maximum Height (may need to be negotiated with neighbor payloads):30 cm (approximately 12″)
Supplied Voltage:26-30 VDC
Available Current:0.5 Amps
Maximum serial downlink (bitstream):4800 bps
Serial interface:4800 baud, RS232 protocol, DB9 connector
Analog downlink:1 ADC Input 0 to 5 VDC
Discrete commands:Power On, Power Off and 1 additional command
Analog & discrete interfaceEDAC 516-020
  
Large Student Payloads: 
Total number of Positions availableup to 8
Maximum Weight:20 kg (44 lbs)
Maximum Footprint (must include mounting structure):38 cm x 30 cm (approximately15″x12″)
Maximum Height (may need to be negotiated with neighbor payloads):30 cm (approximately12″)
Supplied Voltage:26-30 VDC
Available Current:2.5 Amps
Maximum serial downlink (bitstream):4800 bps
Serial interface:4800 baud, RS232 protocol, DB9 connector
Analog downlink:1 ADC Input 0 to 5 VDC
Discrete commands:Power On, Power Off and 1 additional command
(It may also be possible to negotiate up to 4 additional command pairs; i.e. F1 on, F1 off)

HASP Small and Large Payload PlatesEach student team accepted for flight on a HASP mission will be shipped either a “small” or “large” payload mounting plate (see figure).  each plate is constructed of 6 mm thick PVC with a “keep out” area marked around the parameter and holes in each corner for bolting the plate to HASP. Within the allowed region of the plate the payload can be mounted and wired as necessary.  Also provided on the plate are DB9 and EDAC 516 connectors with wiring pigtails to provide the telemetry, power & commanding interface.   Details about the mounting plate and electrical interface can be found in the HASP Student Payload Interface Manual.
