UVS Direct
Juno UVS Module: UVSDirect
This module allows the UVS team to connect their 8051 or 8051 simulator
to the GSEOS software without the hardware SBC.
The connection to the 8051 (simulator) will be a GSEOS socket
connection. GSEOS will act as a network client and connect to the
UVS server.
TLM Data
Data from UVS is expected to be a sequence of IP packets. The incoming
network data will be forwarded into the UVS_TLM_LS_RAW block. The
UVSDirectDecoder will synchronize the packets using some of the
constant IP header data and generate the SBC_IN_TLM_LS block. This
block is then decoded the same way as if it was supplied by the SBC.
Command Data
GSEOS command data will be generated using BIN_CMD_IDP blocks. The UVS
team will generate this block according to their command syntax.
This block will be decoded into proper command transactions into the
SBC_OUT_CMD block. Since this block contains ETF header information
we generate the UVS_CMD_IP block that only contains the IP packet.
The UVS_CMD_IP block will then be transmitted over the network
connection to the UVS server.
In order for JunoBios to process the command queue and to generate
command transactions it requires a periodic ETF STATUS message from
the SBC. Since the UVSDirect connection doesn't have an SBC we
simulate the SBC with the SBCSim software module. This generates nominal
ETF STATUS messages which in turn advance the time properly and process
the command queue so the UVS commands will be transmitted to the
UVS server.
