Yes frameworkd ogpsd has some info about it:

# Feed GPS with position and time
self.send("AID-INI", 48, {"X" : pos.get("x", 0) , "Y" : pos.get("y", 0) , "Z" : pos.get("z", 0), \
          "POSACC" : pacc, "TM_CFG" : 0 , "WN" : wn , "TOW" : tow , "TOW_NS" : 0 , \
          "TACC_MS" : tacc , "TACC_NS" : 0 , "CLKD" : 0 , "CLKDACC" : 0 , "FLAGS" : flags })


# Feed gps with almanac
if self.aidingData.get( "almanac", None ):
    for k, a in self.aidingData["almanac"].iteritems():
        logger.debug("Loaded almanac for SV %d" % a["SVID"])
        self.send("AID-ALM", 40, a);

Good to know that the hope is not lost! :-)

But where do we get this almanac data? Can we redistribute what
u-box.com sends us?
